Once you're past the fundamentals, if find yourself interested in high-performance networking, I recommend looking into userspace networking and NIC device drivers. The Intel 82599ES has a freely available (and readable!) data sheet, DPDK has a great book, fd.io has published absolutely insane benchmarks, ixy [1] has a wonderful paper and repo. It's a great way to go beyond the basics of networking and CPU performance. It's even more approachable today with XDP – you don't need to write device-specific code.

https://github.com/emmericp/ixy/blob/0e00605be4153b06df06184... Looks like you're compiling C code with -O2. Does Rust build set -O3 on clang? Did you try -O3 with C? I know it's not guaranteed to be faster, just curious.

ixy is a nice project for developing an understanding of user-space network drivers. https://github.com/emmericp/ixy

Swift's ARC implementation has a little bit of performance catchup to do in regards to tracing GCs. https://github.com/emmericp/ixy

I heartily recommend this talk. It and the corresponding proof-of-concept Intel userland packet processing driver[1] went a long way for me in removing a lot of the magic from low-level network packet handling and device management in Linux. [1] https://github.com/emmericp/ixy
