Split iouring_linux.go into three build-tagged implementations: 1. iouring_iceber_linux.go (-tags iouring_iceber) iceber/iouring-go library. Goroutine-based completion model. Known -72% write regression due to per-op channel overhead. 2. iouring_giouring_linux.go (-tags iouring_giouring) pawelgaczynski/giouring — direct liburing port. No goroutines, no channels. Direct SQE/CQE ring manipulation. Kernel 6.0+. 3. iouring_raw_linux.go (default on Linux, no tags needed) Raw syscall wrappers — io_uring_setup/io_uring_enter + mmap. Zero dependencies. ~300 LOC. Kernel 5.6+. Build commands for benchmarking: go build -tags iouring_iceber ./... # option A go build -tags iouring_giouring ./... # option B go build ./... # option C (raw, default) go build -tags no_iouring ./... # disable all io_uring All variants implement the same BatchIO interface. Cross-compile verified for all four tag combinations. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
