Sven Taute 8ef6d6a8f2 encoding/base32: increase performance and code reuse ... Add benchmarks for the Encode/Decode functions operating on []byte and increase decoding performance by removing the calls to strings.Map/bytes.Map and reusing the newline filtering code that is used by NewDecoder. Cut allocations in half for DecodeString. Comparison using the new benchmarks: name old time/op new time/op delta Encode 16.7µs ± 1% 17.0µs ± 2% +2.25% (p=0.000 n=9+9) EncodeToString 21.1µs ± 1% 20.9µs ± 1% -0.96% (p=0.000 n=10+10) Decode 141µs ± 1% 54µs ± 1% -61.51% (p=0.000 n=10+10) DecodeString 81.4µs ± 0% 54.7µs ± 1% -32.79% (p=0.000 n=9+10) name old speed new speed delta Encode 492MB/s ± 1% 481MB/s ± 2% -2.19% (p=0.000 n=9+9) EncodeToString 389MB/s ± 1% 392MB/s ± 1% +0.97% (p=0.000 n=10+10) Decode 93.0MB/s ± 1% 241.6MB/s ± 1% +159.82% (p=0.000 n=10+10) DecodeString 161MB/s ± 0% 240MB/s ± 1% +48.78% (p=0.000 n=9+10) Change-Id: Id53633514a9e14ecd0389d52114b2b8ca64370cb GitHub-Last-Rev: f4be3cf55c GitHub-Pull-Request: golang/go#30376 Reviewed-on: https://go-review.googlesource.com/c/go/+/163598 Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>		2019-09-11 00:56:39 +00:00
