I'm getting wildly inconsistent results with iperf. io_uring-echo-server and rust_echo_bench gets me: Benchmarking: 127.0.0.1:12345 50 clients, running 512 bytes, 60 sec. Without alloc tagging: 120547 request/sec With: 116748 request/sec https://github.com/frevib/io_uring-echo-server https://github.com/haraldh/rust_echo_bench How's that look to you? Close enough? :)
