I b= uilt Postgres with musl. I used version 1.1.0. That works well and I've= been distributing musl Postgres in production.

I = still have an install running a previous build using standard libc from and= old 2.4 kernel build. The "native" build runs 14x faster. And th= is is not trying to do anything fancy, just sequentially reading records fr= om a 400 MB Postgres table.

native: 0:25
musl: 5:42

I know my musl version is dated but is= this slow performance to be expected?
