Description

Hey, I recently benchmarked using jemalloc on my NUMA servers, and the difference was quite large. Using the system allocator I got 710k req/s, while with jemalloc I got 830k req/s. That's 17% faster just by dynamically linking with a library.

Anyone else tried this?

Contributor guide

Research direction
