Some interesting preliminary timing of @musllibc's posix_spawn vs fork+exec shows it ~25x faster for large parent processes. (~360us vs 9ms)

@RichFelker@musllibc posix_spawn (CLONE_VM) speedup is prop to mem used right? What parent size for 25x speedup? Do you have a progression?1 reply 0 retweets 0 likes -
Replying to @pixelbeat_
@pixelbeat_ Yes. posix_spawn wins even with trivial static binary and no allocations, but the ~25x is around 40mb in small mappings.1 reply 0 retweets 1 like
@pixelbeat_ For trivial static binary, it's 280µs vs 450µs on the system I test on.
