is Wine with -O3 and -march=native a placebo?
is Wine with -O3 and -march=native a placebo?
For nerd purposes I've been trying to custom compile Wine to see if i can squeeze some performance out of it, i pulled out the -g flag and put in its place -O3 with march native. i don't know how to benchmark properly to see if there at least a marginal gain, so idk if it is a placebo or not. tried to search for articles in the subject but found none
has anyone tried it or know an article that explored the subject?
You're viewing a single thread.
IMO there's no point in optimising without being able to measure the results.
A profiler should be able to tell you how much time is spent running the code you're attempting to optimise. It might turn out that the wine runtime code is not a significant factor in performance.
I bet Phoronix has benchmarks of this
i searched phoronix and found nothing, they did other programs whenever a new gcc version launched, they compiled a lot of benchmarks with different flags and measure compile time and program performance, some programs gained a noticeable with -O3 -march=native
