Alpine Linux: Brilliant Linux Distro

Re:Alpine Linux: Brilliant Linux Distro by stabbles on Thursday March 10, 2022 @07:26PM (#30634554)

I've tried alpine's gcc before and it was about 50% slower to compile a bunch of packages. That said, if you compile llvm with MinSize/-Os on glibc distro's it runs 50% slower too, so it's unclear if slowdown is due to musl libc or rather that they optimize for size instead of performance.

Compiling is CPU-bound and doesn't really bottleneck on anything that libc is involved with other than the allocator, so unless musl's allocator is comically slower than glib's, chances are it's just -Os.

This is pretty much -Os. Void Linux provides -O2 builds of GCC for both musl and glibc with a negligible performance difference. I have not benchmarked it lately, but it is clearly below 10%.

I believe musl’s allocator is known for being pretty poor.

musl-1.2.1.tar.gz (sig) - August 4, 2020

    This release features the new "mallocng" malloc implementation, replacing musl's original dlmalloc-like allocator that suffered from fundamental design problems.

https://musl.libc.org/releases.html Rest of the detail in the actual changelog is worth reviewing too

Sounds like my information is out of date!
