Profiler Survey

Four short questions to keep the total time investment to a minimum. I generally don't click through to publish survey response comments so don't worry if your answer doesn't show up. I'll read all the responses for as long as comments are open.

Do you use profiling tools with a .Net framework application that you've written? These can be any managed applications, not necessarily involving WCF.

Is the profiler you use based on sampling or code instrumentation or some other mechanism?

Are you profiling an application that runs on a single machine or on multiple machines?

Are there any particular brands or features of profilers that you really like?
