Testing the speed of ANTS Profiler 4

Published 16 September 2008 8:55 am

Profiling and debugging code inevitably adds overhead, and I know that it can be really frustrating. The overhead can either be small, e.g. the Visual Studio debugger, or massive, as with most performance profilers. A developer may invest in a performance profiler to optimize an algorithm that takes 10 minutes to run, and finds that when profiled it takes 2 hours to run. A top priority in the development of ANTS Profiler 4 was to make it faster than its predecessor and faster than any other profiler on the market.

We have found ANTS Profiler 4 to be about eight times faster than its predecessor, ANTS Profiler 3. It is also 4 to 20 times faster at line-level profiling than other profilers on the market.

I did a few speed tests and I have made a video to show how ANTS Profiler 4 compares to the fastest-known other profiler:

Here it is compared to ANTS Profiler 3:
