I blew it!

I put my lunch on a plate, throw it in the microwave and about a minute later, there was a loud crack. The plate was split into two down the middle. First time in my life I have broken a plate like that... how bizarre.

Network problem

Ever since late July I have been involved to diagnose a performance problem. After a few weeks of back and forth, dicing through the numbers and adding instrumentation to our code, it boils down to network delays in our .Net remoting calls. At that point I should have throw my hands up and pass the problem to the Network engineers. Unfortunately that person was on vacation and I need to carry on. After a bunch of trials and errors and flipping around options on the network driver level, the problem seems to be related to SNP/TOE. So next time you see a network slowdown, check if SNP/TOE is turned on.

it might be obvious for others

This is definitely not obvious for me.

I did some performance tuning for our web app and cached some pages a while back. I did this:

<%@ OutputCache Location="Any" Duration="3600" VaryByParam="none"%>

I was going through the IIS logs as see that the page in question is still being requested a lot. Changing it to

<%@ OutputCache Location="Any" Duration="3600" VaryByParam="None"%>

does the trick. It seems implicit and I have definitely seen other people using the lower case version. But the attribute is CASE-SENSITIVE!!!
