Subject: musl 14x slower?

Please cc me on replies.

I built 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 this is
not trying to do anything fancy, just sequentially reading records from 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?
