SOCKMAP - TCP splicing of the future
Summary
Cloudflare's SOCKMAP article explains a Linux kernel eBPF-based SOCKMAP for TCP splicing, showing a kernel-level offload approach to move data without user-space copies. It provides historical context, implementation details, and benchmarks comparing naive read-write, splice, io_submit, and SOCKMAP, concluding SOCKMAP isn't ready for prime time yet but shows promise.
