Understanding Profiling Times

Hi Bill,

ANTS Profiler slows applications down tremendously, which, although
we've done our best to minimize the effects, is going to happen because the
application needs be be a dubug build, plus there is overhead in monitoring
the CLR.

We have a built-in algorithm that should compensate for the profiling
overhead when you get the results back, so there shouldn't be a discrepancy
this large. The only exception is if you have got a lot of recursion in your
code. This is explained in the FAQ: http://www.red-gate.com/dotnet/faq.htm.

Hopefully that is the cause of the inflated times.

Regards,
