I understand you aren't going to be able to give me a specific answer, but I am kind of stunned at this point...

I work on a library that has competitors. Our APIs are pretty similar. I call MyLibrary.MethodA() 1,000,000 times. It takes 1000ms. I call MyCompetitor.MethodA() 1,000,000 times and it takes 150ms. Both in Debug / Any CPU.

I'm trying to figure out where my overhead is. So in MethodA() I tried returning just null at the beginning. That was already 16ms. MethodA calls an internal method which calls another one, etc. Basically, the only thing I'm doing at the top level methods is checking the params for null. Then I lock a dictionary and do a TryGetValue. At this point I start getting to the method that starts doing real work. I'm already at 195ms and am returning null.

How is that even possible? The other guy is returning 150ms and actually doing the work. I'm at 195ms and returning null from an empty method???
