bench

Overview ¶

Command bench is the ossein guest microbenchmark suite: one static linux/arm64 binary that runs a single benchmark selected by --type, so the whole suite is a single artifact to cross-build and mount into a container. Each benchmark lives in its own file (syscall.go, forkexec.go, forkonly.go, fs.go, fileio.go) as a run<Name> function; this file only dispatches. Positional args after --type are the selected benchmark's own args, e.g. `bench --type=fs rootfs stat 20000`.
