mempool

This crate provides a fast thread safe memory pool for reusing allocations. It aggressively optimizes for the single-threaded use case, but gracefully supports access from multiple threads simultaneously. In particular, values in a pool may not be shared across threads.

Usage

To use this crate, add mempool as a dependency to your project's Cargo.toml:

[dependencies]
mempool = "0.3"

Benchmarks

This crate currently uses the mempool_get_put_tls approach.

test bench::crossbeam_ms_get_put      ... bench:         105 ns/iter (+/- 4)
test bench::crossbeam_seg_get_put     ... bench:          87 ns/iter (+/- 25)
test bench::crossbeam_treiber_get_put ... bench:          93 ns/iter (+/- 1)
test bench::mempool_get_put_tls       ... bench:           1 ns/iter (+/- 0)
test bench::mpmc_get_put              ... bench:          30 ns/iter (+/- 0)
test bench::mutex_get_put             ... bench:          46 ns/iter (+/- 0)

Motivation

I needed a very fast way to reuse allocations across multiple threads, potentially optimizing single threaded use over multithreaded use.
