描述

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?

研究方向
The issue asks for benchmarking results comparing jemalloc vs system allocator on the Drogon framework. To investigate, set up a Drogon server on a NUMA machine, compile with jemalloc linked dynamically, and run benchmarks (e.g., using wrk or similar). Compare requests per second and latency. Look at existing benchmark scripts in the repository, if any. Since no specific benchmark code is provided, you would need to create a minimal server and run tests.
