Only the YCbCr benchmarks show significant changes. The other benchmark changes look noisy. The PixOffset and YOffset calls were previously already inlined by the gc compiler. COffset was different because it's more complicated than YOffset, and the switch inside the COffset body is redundant when you already know the src image sratio. http://golang.org/src/image/ycbcr.go?s=2377:2414#L77 benchmark old ns/op new ns/op delta BenchmarkScaleLargeDownNN 1037504 908236 -12.46% BenchmarkScaleLargeDownAB 3196568 2735776 -14.42% BenchmarkScaleLargeDownBL 357165552 311463393 -12.80% BenchmarkScaleLargeDownCR 649403305 544985134 -16.08% BenchmarkScaleSrcYCbCr 3204063 2699147 -15.76% BenchmarkTformABSrcYCbCr 2155142 1968540 -8.66% BenchmarkTformCRSrcYCbCr 11672625 9865358 -15.48% Change-Id: Ifa109363a1282ab114b2fdb0b577dcafef927333 Reviewed-on: https://go-review.googlesource.com/7880 Reviewed-by: Rob Pike <r@golang.org> |
