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.
