Performance Advice, Southern Style

While I was at PDC2008 I was introduced to Keith and Woody -- pretty soon there was a microphone in front of me and we were doing a podcast. Now I already liked these guys but when they used a picture of me from about 1998 I really liked them a lot more.

Is Performance a "functional" requirement?

We had an internal thread on this yesterday, maybe I was a little too glib but here is what I had to say about the topic [edited so it can be read standalone] The original question, “Is performance a functional requirement” is highly unexciting for me.

Even though I've been doing general architecture work on Visual Studio for nearly a year now, my friends in DDPERF are still plugging away on performance problems and finding some interesting results. This most recent thread is very interesting because

Shutdown Is No Time For Spring Cleaning

I think my current performance pet peeve is shutdown. Assorted flavors of it, they all seem to have the same kind of problem. Sometimes we're stuck with it... but maybe we shouldn't be? This is one time when our basic training, which normally I love so

Performance Quiz #13 -- Linq to SQL compiled query cost -- solution

Well is there really a "solution" at all in general? This particular case I think I constrained enough that you can claim an answer but does it generalize? Let's look at what I got first, the raw results are pretty easy to understand. The experiment I

Performance Quiz #13 -- Linq to SQL compiled queries cost

I've written a few articles about Linq now and you know I was a big fan of compiled queries in Linq but what do they cost? Or more specifically, how many times to you have to use a compiled query in order for the cost of compilation to pay for itself?

Performance Threat Models

I've been meaning to post this for ages and somehow I kept forgetting. J.D. and I have long thought that many of the techniques used to do a security threat model are actually directly applicable to doing performance analysis as well. The idea of threats

File Open Performance -- Beware of 'Extensions'

Here is a little interchange I had a few days ago; "Nick From Chicago" graciously allowed me to share it nearly verbatim. I'd like to claim that I was psychic in diagnosing this but as you can see in the thread it isn't the first time I've run into this

Performance Improvements in Visual Studio 2008

It seems I'm doing a lot of referral postings this month and I've got a couple more for you. This is the first one, near and dear to my heart because I worked with Cameron on some of these (and he didn't mention me at all, *sniff*) especially the performance
