Question is pretty straight-forward:
You just finished writing a bit of code, and it doesn't quite meet your performance demands, so you run it through a profiler to find out where you need to trim fat. What are you really hoping doesn't show up in your profiler results?
For me, I just got the result that memory allocation is accounting for roughly 75% of my runtime. This really is one of those things that I hope not to see, mostly because it's one of those kinds of problems that can't really be addressed in one place, and is a sign that everything everywhere needs changed.
