Oleg Zaytsev	280eaf33f0	Use global string map for MatchType.String() (#9237 ) * Use global string map for MatchType.String() We were unnecessarily creating a new map for each call of String(). This is a 10x improvement in MatchType.String() performance in time, from 53ns to 4ns on my i7 laptop, and I guess that this method is being called quite often so why throw out the resources. I was surprised that benchmark says that there are no allocations made in the old version. I also tries using `//go:generate stringer` and the result is even better, at about 2.8ns, but having to keep the generated code updated isn't worth the change (at least it's bigger than a small change I was intended to do) Benchmark comparison: name \ time/op old global_map stringer MatchType_String 53.6ns ± 1% 4.1ns ± 1% 2.8ns ± 1% name \ alloc/op old global_map stringer MatchType_String 0.00B 0.00B 0.00B name \ allocs/op old global_map stringer MatchType_String 0.00 0.00 0.00 Old benchmark: goos: darwin goarch: amd64 pkg: github.com/prometheus/prometheus/pkg/labels cpu: Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz BenchmarkMatchType_String 21766578 54.36 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 21742339 53.28 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 21985470 53.37 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 21676282 53.50 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 22075573 53.33 ns/op 0 B/op 0 allocs/op PASS ok github.com/prometheus/prometheus/pkg/labels 6.252s New with global map: goos: darwin goarch: amd64 pkg: github.com/prometheus/prometheus/pkg/labels cpu: Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz BenchmarkMatchType_String 283412692 4.129 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 294859941 4.091 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 295750158 4.113 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 282827982 4.072 ns/op 0 B/op 0 allocs/op BenchmarkMatchType_String 292942393 4.047 ns/op 0 B/op 0 allocs/op PASS ok github.com/prometheus/prometheus/pkg/labels 8.238s Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com> * Use array instead of map Since MatchType is an iota type, we can safely use an array here.
