We should use `(*regexp.Regexp).MatchString` instead of `(*regexp.Regexp).Match([]byte(...))` when matching string to avoid unnecessary `[]byte` conversions and reduce allocations. func BenchmarkMatch(b *testing.B) { for i := 0; i < b.N; i++ { if match := versionRe.Match([]byte("v1")); !match { b.Fail() } } } func BenchmarkMatchString(b *testing.B) { for i := 0; i < b.N; i++ { if match := versionRe.MatchString("v1"); !match { b.Fail() } } } goos: linux goarch: amd64 pkg: go-micro.dev/v4/api/handler/event cpu: AMD Ryzen 7 PRO 4750U with Radeon Graphics BenchmarkMatch-16 11430127 127.4 ns/op 2 B/op 1 allocs/op BenchmarkMatchString-16 12220628 97.54 ns/op 0 B/op 0 allocs/op PASS ok go-micro.dev/v4/api/handler/event 3.822s Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>
