Summary0000849: Decrease tracing/profiling overhead
DescriptionAs mentioned, I get 200% to 600% execution timings when tracing a script; is it at all possible to reduce this overhead? Especially since I'm guessing it's roughly linear with the number of function calls, it makes profiling scripts with large number of funcalls difficult.

For instance, I have a script that runs under 400ms, but does in excess of 100K calls; this leads to a traced execution time of 2s. The functions at the bottom of the call tree (those that get called a lot) pull a lot of weight for being traced, although execution in a timed cycle shows they don't pulled nearly as much weight as the profile reports.
TagsNo tags attached.

This is definitely on the plan!

Sounds like a magic "make things faster" feature request. I am not a magician :-รพ. In the future, profiling will happen, but this issue is not really actionable, so I'm closing it.
