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 problems in the cases with "Venus" (the ASP.NET project system), and one of my teammates, Hazim Shafi, worked with VB on many of the other issues too.  I'm very happy with what we managed to do, although there's always more :)

Anyway, without further ado, here's Cameron McColl talking about performance improvements VB made in VS2008.
