coz VS uvw

But let's take the guesswork out of profilers. Use Coz. It's a causal profiler that performs experiments to determine what code would see the greatest performance improvement of the whole program if made faster. There's a video in the link; I think the best demonstration they had was a program that saw the greatest improvement by optimizing a function that ranked #30 by a sampling profiler.

Coz. It's in a Debian package so you don't have to build it. Watch the video embedded in the page I linked; I;m all about profiling, but the devil is if you're not a statistician, you don't know how to read profiler results.

I think https://github.com/plasma-umass/coz solves most problems related to noise in benchmarks.

Perhaps you're thinking of the coz profiler (https://github.com/plasma-umass/coz)?

I was thinking of doing some kernel profiling, and stumbled upon this interesting repo: https://github.com/plasma-umass/coz

I'm pretty intrigued by the concept, and was wondering if anyone here tried out Coz.

Could it be an issue of binary layout? Have a look at the coz profiler which has a rust port.

Have you tried this wrapper? https://github.com/skypjack/uvw
