ebpfbench
profile eBPF programs from Go. Requires Linux kernel 5.1 or greater.
Examples
cd examples/bench
go run -exec sudo ./bench
Usage
ebpfbench augments the standard testing.B object.
func BenchmarkExample(b *testing.B) {
eb := ebpfbench.NewEBPFBenchmark(b)
defer eb.Close()
// setup eBPF programs using cilium/ebpf, gobpf, or other libraries.
fd := prog.FD()
eb.ProfileProgram(fd, "")
eb.Run(func(b *testing.B) {
// exercise programs here
})
}
The results per program will be output in the standard go benchmark format.
