feat: Use `jemalloc` as allocator

Open larseggert opened this issue 3 months ago • 6 comments

Gecko uses (it's own flavor of) jemalloc, including for Rust. The intent here is to get the standalone demo client and server, and the benchmarks, closer to Gecko.

As discussed with @valenting.

TODO: Is there a way to put this behind a feature or something, so that the tikv-jemallocator crate doesn't become part of the Gecko deps when vendored in?
