Tom’s hardware has been benchmarking an Athlon 64 X2 4800+ with 2.4 GHz against an Intel Pentium 840 EE with 3.2 GHz. You can get the details of the test results and configuration, at this link.

What is very interesting is the the AMD proc is running at 2.4GHz and the Intel proc is running at 3.2GHz. Conventional wisedom would dedicate that the faster clock rate would mean more work would get done and that the Intel proc would be the winner, right! I think it is safe to say that this is the way that most folks would qualify a Processor?

The current results that the folks at tom’s hardware have are:

• “Data compression with WinRAR: the AMD system has 29.5% better performance;
• MP3 encoding of the CD: AMD system has 4.7% better performance;
• DivX encoding of the DVD: AMD system has 28.2% better performance. “

and these results are with the Intel proc having HT enabled, which means 4 virtual CPU’s and this *feature* is not available from AMD :D

You gotto love the new architectures that AMD are using in their procs, it is just so clever and fast; and I am a huge fan. Its really clever stuff, esp. the HyperTransport.

But it does bring up the interesting question, how easy/hard is it going to be to measure/quantify/decide which processor is right for you? While clock rates was a nice simple way (possibly too simple of a way) to do it, now that clock rates have reached a plato for the next few years, its not the easiest thing in the world to articulate to someone, as we have been gorging on a diet of faster means better for years?

Perhaps we can use something like, they work smarter and not faster  It looks like AMD will be the Gamer, etc.. proc of choice for the next few months, until some of the new Intel procs emerge.

Many thanks to NIMTUG in belfast for the invite and to the many folks that attended the talk. Its very hard to give a talk, with a fridge full of beer at the bottom of the room

You can get the slides for the talk at this link.

Since I feel that many of the questions were quite pertinent and relevant to usergroups in IRL, I thought I would jot down a few notes and responses; hopefully help out.

To start with the low lying fruit:

– Yep my blog is a mess, sorry, I have been adding code/features to the DasBlog engine (such as delayed publishing, fixing a few bugs, a new stats engine that uses SSB and Yukon for the heck of it and a weak attempt at a port of the core engine to Whidbey), and hence some of my downloads have been broken, I will look into this and either revert pack to the offical release and/or fix the problem. So give me a few days on this and the downloads will be fixed.

– Again we have lots of new folks joining the usergroups that have a serious want for information on VC++ information, in regard to VS2005 and how to move VS6 VC++ code to .NET and/or the new VC++ in VS2005. Give me a few days on this one and I will put together a collection of links etc… that I have found very useful and hopefully they will be a help.
For me, I am very delighted to hear different folks mention this at the last number of usergroup sessions I have been at (in Dublin and Belfast) and I totally agree the VC++ team should be more visible with what they are doing, as there is not as much material out there when compared to other langusages, but I think the reason for this is fairly apparent.

– A HUGE many thanks to the folks that are still giving me feedback on the System.Transactions talk. As I have said to many folks before, I personally perfer concept based talks, as I like to give some suggestions on perhaps some new ways of thinking about patterns, uses of technology etc I really do very appreciate the fact that many folks like the way that I tackle the concepts first and it seems really helped folks think of transactions in a totally different way.

– For me, probably the best question of the night, happened before the talk even began. “Has WinFx become very confusing” ?
My answer, ABSOLUTELY. Once more with feeling, AAABBBBSSSOOOLLLLUTTEEELLLYYY? For me it is becoming very hard to understand what is being downstreamed, will it be downstreamed to W2K3/XP or will it be W2K3 R2 etc………  

There was many other interesting things happened at the talk, such as an ex-member of the Avalon team was present at the talk, WOW.  And did I mention the fridge full of beer at the end of the room!!! Damn, should have brought a camera.

Also, there was a few areas that I had to skip, as I was running out of time, mea culpa, but since many folks were new to SO, I thought it would be best to spend more time on that.

Examples would be:

– I did not cover in depth how Indigo is host agnostic, in that it can be hosted in IIS, EXE, Windows Service (sometimes still referred to NT Service), plus many other options.
– Yep, I did not cover WAS (the Windows Activation Service). This was mainly due to time, but in fairness this is probably one area that is probably subject to the most change over the next while.
– Other things I have to followup on include, the P2P stuff from MS (Rob might give me a hand with this one), lots of Q’s on Interop (both on papers/examples), custom transports/bindings in Indigo (which is a good blog entry I think), some Q’s about E12 (the next version of Exchange, I don’t think there is much out there yet, as its RTM is a bit out, roughly Longhorn Server AFAIK), some of the papers I referenced during the session, more material on SO (as some folks had never heard of it before), plus many more questions (the NIMTUG guys have made a list and Damien will forward it on to me) and If I missed your questions, please let me know.

As I am going to off for the next few days, it will probably be Monday before I get back to answering all of these, so please bear with me.

Many thanks again for the great questions and feedback, it gave me lots of ideas about what I perhaps should change in the presentation (but it is a very large topic) and also blog a little about. Especially interop with services using today’s stack, as you generally have to fight with the tools so much, it is not even funny! Lots of folks seem to be having issues here and there is quite a bit out there, such as the latest version of the MSDN magazine, where Aaron Skonnard has written an excellent article on this topic.

I was very particularly interested to hear the comments about VC++, Biztalk and IT-Pro. Yep, this is probably something that needs more attentation across all of the usergroups, as it is not the first time I have heard this feedback.

When I get the time, I will update this blog entry next week and follow up with more details that will hopefully help with the questions that many folks raised.

Ciao for now,

Rgds,

<update> I see that this issue has been resolved and that have new stock in place. Info via Volker Will’s blog </update>

I heard about this last week (from a buddy in Texas), but it seems that the Register have also picked up on it as well.

I was actually floored when I heard that AMD have actually already run out of the promotional hardware (i.e. Athlon64 3200+ and Windows XP x64 Edition for just $250 and a server system with two Opteron 246 chips and Windows Server 2003 x64 Edition for just $500)  for the AMD Tech Tour and they are only 4 or so into the 13+ cities they are visiting in this promotional tour of the US and Canada. I won’t even mention the fact that they choose not to come to any region outside of the north american continent.

Not so good for those folks in the other 9+ cities where they are expecting some good discounts. I know AMD hardware (as well as dual-core procs) is hard to get right now (especially in Europe) but come on AMD? What were you expecting? No one was going to take up the offer?

sigh!

As I seem to be on a bit of a HTTP traffic binge this week, looking at why my angle brackets cannot get between systems, I have been heavily using the Fiddler tool and I would highly recommend.

You can get the Fiddler bits at this link

ps

btw, its very useful to track down malware as well. Its very interesting to see how much info get transmitted when you click a link on a browser and/or use a browser toolbar.

This recently came up in a conversation I had during the week.

How do I manage a IIS6 from an XP workstation?

There is a version of the IIS6 manager specifily aimed at XP. You can download it from this link.

As we all converge on port 80 traffic to make stuff work and communicate with each other, at some stage we all benchmark and test the performance of the web property, right

While performance testing a web site/service is always a tricky business, as there is always a feeling that it is artifical in nature and does it really reflect what takes place in a live production system?

For me, one area that comes up quite a bit is the (default) settings of Windows and .NET when it comes to perforamance testing, whether it be with ACT, LoadRunner, etc…..

While there is lots to think about, such as the configuration of NLB, NAT, firewalls etc… One of the things that can be easily over looked, is the simple statement in the HTTP specs, where it states for HTTP implementations “A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy” and the inverse of this is also true.

So, when doing performance testing, perfectly acceptable live production settings can cause you some issues, and perhaps even soak up cycles while you chase a “perceived” performance issue, when it does not exist.

So, it is always useful to augment the default settings in your test environment, and add your client performance test machines to the “ConnectionManagement” configuration of the network setting of the Fx. IMHO, I would not alter the defaults, as they are there in my opinion to reduce the attack surface for a DoS attack.

HTH,

Have not tried this yet, but it is an interesting question?

Will the Whidbey threadpool recognise that it is on a system with multiple cores? It probably will, but I still have to find documentation/links that explicitly states this?

IMHO, its uber important that it does, as the traditional DP server market is soon going to have 4 execution cores and not the traditional two.

If it is not, then perhaps things like ASP.NET, ASMX etc… will perhaps have a less than optimial configuration for the typical dual proc server that gets 4 execution cores? Just a thought, maybe it doesn’t make a difference, but it does raise an interesting question.

For sure, 25 threads per proc. is the magic number for server apps; in general anything above that causes performance degradation (in general), but when the processor die has multiple core, what should the value be? Or does the value still remain valid? If so, what is the performance charteristics of running only a default max of 50 threads on a box with 4 execution cores? Considering that most programming today is done in a sync. manner, having only a default max of 50 threads on a DP box raises some interesting questions? Today, when you move out of the traditional 2 execution core market (i.e. your standard dual proc machine that 90%+ of the market uses) and go into the 4 proc boxs you typically have to throttle down the default settings, but with more that one execution core in a processor die, which way does the default setting work? Per processor die or per processor core?

Just curious, as I have not seen it mentioned yet? I probably will try this out over the next few weeks, but if anyone knows, I would be keen to know?

With the release of SP1 for W2K3 , there was a number of changes to the HTTP API, which I find very useful.

There is some very obvious changes like the support for 64bit, but there has been lots more as well.

The basic list of these changes are:

• Improved Performance and Scalability
• Enhanced HTTP Error Logging
• HTTP API Kernel-Mode SSL Support
• HTTP API Parser Enhancements
• HTTP API Parser Exceptions
• WOW64 Support

Examples of the changes are the default hard limit of simultanous connections that was around 8000 or so (AFAIK). Obviously pre-SP1, you could overide this behavior (with the MaxConnections registry key), but thankfully in SP1 this default hard limit has been removed, with the only constraint being the physical resources of the tin (which on a good x64 kit, is very high indeed). For example, in this report on a standard 4way HP box, they cranked up x64 Windows to over 160,000+ open TCP sesssions, SWEET.

Also there has been lots of changes to the logging and the very strict parsing of HTTP headers. For me the new knobs to change the parsing behavior/compilance to HTTP 1.1 is a welcome addition.

With the following keys – AllowWeakHeaderNameSyntax, AllowWeakHeaderValueSyntax,  AllowCaseInsensitiveVerbs, AllowUnEscapedRestrictedChars – you have some very useful options for the rare case that you are using a funky piece of technology and making calls to a web service on W2K3. Obviously its better to try and make the funky technology generate valid HTTP 1.1 headers, but sometimes this is not an option and I have been bitten by this more than once over the last few years.

One of the hidden treasures within SP1 for W2K3, is a new registry key that enables the processing of SSL to be performed in Kernel mode, as opposed to the current User mode process.

This optimisation gives a nice performance boost, but it pales in comparsion when you enable this feature on a x64 version of Windows 2003. Here you will find a comparsion of x86, x64 of Windows and the 64-bit 2.6.7 kernel in RHEL 4.0 and Solaris 10 64-bit Edition.

To enable the feature, you have to use the following reg key.

HKLM\System\Current Control Set\Services\HTTP\Parameters\EnableKernelSsl = (DWORD)1

After that...do a quick net stop http & net start http and Kernel Mode will be used tranparently.

My good friend, Eamon O'Tuathail of Clipcode ,  – current EMEA Security Champion – has a great idea, that a bunch of us should join together and write a number of freely available public domain books.

The first book we are going to tackle is ASP.NET v2 and you can get the description for the book at http://www.clipcode.cc/books/id/005/index.html

A number of us are already signed up, including Pascal, Kieran, plus a few others

ASP.NET V2 is not the only book on the way, there is lots more, including The Agile Software Development Process, Active Directory For Developers, and more to come. I will blog the complete list later.

If you would like to help write any of these books, please contact publisher@clipcode.cc or place a comment below.

On the latest MSDN TV .NET Show, Robert Hess talks to Larry Sullivan, Volker Will, and Kevin Frei about 64bit Windows.The guys have done a nice piece on covering the 64bit Windows space, especially about how 32bit dll’s are not callable from 64bit processes, as well as how to properly handle ints and pointers, plus lots more.

As someone that has been through the 16–bit to 32bit migration process, I very much agree with them on the fact that the migration process to 64bit is soooo much simpler.

Good viewing and I would highly recommend.

Chris Menegay has blogged about some Team System News from TechEd. Some of the news includes that if you are a “MSDN-U subscriber and want Team Suite, it will only be $1000 more per year (retail price), as opposed to the $2299 previously stated”.

More details are covered in Chris’s blog.

Richard Godfrey has blogged an interesting post on “Is it legal to be an 'Architect'?”, in the context of the title of ‘Architect’ being protected by English Law.

It seems the UK act in question is Architects Act 1997, with some guidance on its use can be found at this link

As pointed out by Richard, the Architects Registration Board (http://www.arb.org.uk), have commented on the use of architect in the ICT industry.

“In particular, the Board is aware of widespread use within the computer and IT industry of the word “architect” being incorporated into certain job descriptions, eg. “Systems Architect” or “Software Architect”. While such use may be a technical breach of the Act, the reason for and intention of continued regulation of title is principally to ensure that consumers of architects’ services are guaranteed a certain standard and quality of work.

It was never the intention of the Act to regulate the title for its own sake. The Board therefore takes a pragmatic view, and accepts that the use of the word “architect” causes no concern when used in a context which is clearly not related to the design and construction of buildings.”

I wonder is there such a law on the Irish statute books, probably not, phew!!  

Maybe I should cut back on using buildings as analogies, just to be on the safe side

or maybe on second thought……

What would be useful, is a more formalised way to define the architect moniker and better establish the taxonomy, as it is a widely used term and perhaps establishing a better definition of the word architect and how it related to the design and construction of Buildings systems, would clean up the huge variety of roles and the many defintions (for Enterprise, Solution, System, Application, Software and Technical architect). Certainly the upcoming certified architect programme, especially with its strucuture/process being close to that of a PhD board, is a huge leap in the right direction. I have always had great admiration for certain certifications in the industry, such as the Cisco’s CCNA, CCNP and CCIE, these are ultra hard to get and you earn your strips with them.
