Timeline includes profiler overhead?

I have observed that while my application normally consumes 1 CPU, the Performance Profiler suggests that it consumes close to 2 CPUs (i.e. the timeline is mostly close to 200%).

I think that the timeline is counting the overhead of the profiler thread. Is this the expected behaviour? Any idea on how to get something close to my real CPU usage?




  • It may well be that the timeline is indicating higher CPU usage than you would expect- it is really only meant as a rough guide. The profile does, by default, actually take off over-head using a heuristic that is usually very reliable so the actual data values you see should be more trustworthy.
