December has been a very busy month, so I am sorry that I haven't had time to write anything...
However, Maoni has come out with some very noteworthy material, stuff that is essential to know in order to interpret
the data we are debugging correctly.
There are 3 articles about the difference between perf data reported by different tools (perfmon, sos, etc.), here is hte first one which will link you to the other ones.
On a separate note, the escalation team for windows have also started blogging about debugging (on the native side)
And one of my colleagues has started blogging about common issues in ASP.NET
Don't worry, I'm not going to turn into a link machine:) Just wanted to give you some alternative reading material for X-mas since I won't have time to write up a case study...
