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?
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
Yeap, -O3 is mostly voodoo. Berger has some measurements.
Spoiler: He found your username has a bigger effect on performance than most compiler flags:-)
I think the position of the moon and the sun and the relationship between the two has more effect
