A recent analysis highlights significant performance regressions when using the musl C library, particularly in Rust applications. The author found that musl's default memory allocator is substantially slower than alternatives like mimalloc or jemalloc, leading to performance drops of up to 26% even when using optimized allocators. This performance gap persists across various tasks, with some memory-intensive routines showing even greater proportional slowdowns. Consequently, the author recommends avoiding musl for performance-critical applications and will remove it as a prebuilt option for their own project, Bifrost. AI
