In my previous Post I posted a ZIP file containing 3 videos using the new PerfView tool. Here I add another 2 videos to the collecition. The should be unpacked into the same directory as the first 3 (that is the perfViewVideos directory beside the...

In my previous Post I mentioned the new PerfView tool, which is the tool that I use for most of my performance investigations. If you have clicked tried to access the video's link in PerfView you have probably been disappointed since it currently simply...

I know it is has been a while since my last posting, but long ago I decided that I would not write just to have something to write about but rather only when I had something I really something useful to say. Well do have something really useful to...

About two years ago now I wrote part 1 and part 2 of a MSDN article entitled 'Measure Early and Measure Often for Good Performance'. In this article I mention some 'perf mantra' which is that Every application deserves a 'perf plan' (which and be...

Tomorrow (10/14/2009) I am giving a talk on performance at Microsoft-Campus Paterns and Practices Summit . Below is the abstact for my talk To many developers, high performance development is ‘magic’. It involves multiple metrics (time, memory allocations...

I am giving a .NET Performance talk for the users group at the Royal Bank of Canada, and I am posting the slides for the talk here for future reference. (see power point document attached to this entry below). Anyone who has heard me speak will see...

If you use managed code, and you care about performance, then we want to hear from you. We have not yet shipped the next version (what we call Version 4) of the .NET Runtime, however we are 'locked down' enough that at least a few of us on the runtime...

In case anyone is interested I did an video interview on the runtime in general. This is more about philosophy than technology, but if you are in the mood for some philosophy about the runtime, here is some from someone who has been around from the CLR...

Almost a year ago now I wrote part 1 and part 2 of a MSDN article entitled 'Measure Early and Measure Often for Good Performance'. In this article I argued that if you want to design high performance applications you need to be measuring performance early...

Every year or so, when Microsoft believes it has something useful to say to develoeprs it hosts a Programmer Developer's Conference. It is doing so this year from 10/27 through 10/30. Between Rico Marani, Mark Friedman and myself, we gave a all day talk...

These are the slides that Mark Friedman used to talk about ASP.NET Performance at the Programmer Developers Conference.

These are the slides Rico Mariani used to introduce the all day session we gave on .NET performance at the 2008 Programmer Developers Conference.

These are the slides for the third (of 3) talks I gave on 10/26/2008 at the Programmer Developer Converence (PDC) doing parallel programming with the .NET runtime.

These are the slides for the second (of 3) talks I gave on 10/26/2008 at the Programmer Developer Converence (PDC) memory investigation.

These are the slides for the talk I gave on 10/26/2008 at the Programmer Developer Converence (PDC) on the basics of performance investigation

I just happen to notice that I don't have any links from my blog to some recient MSDN articles I wrote on performance. I want to quickly correct his with this posting. There is actually a very nice summary page that MSDN created that gathers together...

This is a quick plug for a pre-conference session I am giving on 10/26 at Microsoft’s Programmer Developers Conference (PDC) 10/26 held this year in Los Angeles. My talks are part of a all day session that I am giving along with Rico Mariani and Mark...

In a previous posting , I mentioned that .NET V3.5 Service Pack 1 had significant improvements in the Just in time (JIT) compiler for the X86 platform, and in particular its ability to inline methods was improved (especially for methods with value type...

Hurray, its finally fixed! manage code 'just works' from network file share! Now I know that some of you are probably just saying 'who cares' or 'huh?' but for those of us who have hit this problem, this has been a major deployment headache, and I...

What's Coming in .NET Runtime Performance in Version V3.5 SP1 It certainly has been a while since I last blogged. Most of this is laziness on my part, but I can truthfully say that it is partly because I have been busy trying to get the next servicing...

A few years ago now, several of us on the .NET Runtime team where lamenting how unapproachable the code base was for new developers to the team. We agreed that more commenting would certainly help the situation, but that alone was not enough, because...

In my last blog I talked about some of the conditions than need to hold for the cold startup formula ColdStartupTimeMSec = WarmStartupTimeMsec + 4 * NumberOfReads + 20 * NumberMBytes To be accurate. I mentioned that if you have overlap between the...

After my last blog entry on cold startup a reader ( dimkaz ) worried that the formula would not be accurate in many cases. This topic is worth discussing in some detail because it pretty common to apply formulas outside the assumptions implicit in...

Well it is has been a while. I see now that it is been getting close to 1/2 a year since I last posted. Sigh. It is so easy for other things to get busy and not to blog. I have resolved to try to be a bit more methodical about and insure that I write...

This article is the beginning of a new 'Introduction to Programming' topic for my blog. The BouncingBalls example. Basically, I have decided to try to teach programming to a set of teenagers from my son's junior high school, and this topic will be...
