Egon Elbre	9de13e37e9	f32: add Affine2D.Split ... splitTransform func was creating multiple copies of f32.Affine2D due to not having access to the internal and passing around non-pointer. This makes splitTransform from ~8ns to .Split ~2ns. It seems that the non-pointer receiver was ~0.6ns slower in this case. Signed-off-by: Egon Elbre <egonelbre@gmail.com>	2022-07-02 07:04:47 +02:00

Egon Elbre	24d6f3fb65	f32: optimize Affine2D ... encode/decode seem to introduce significant overhead. Inline them manually. It'll make code harder to read, however the performance wins are significant. name \ time/op before after delta TransformOffset-32 2.64ns ± 0% 0.25ns ± 0% ~ (p=0.100 n=3+3) TransformScale-32 2.64ns ± 0% 0.25ns ± 1% ~ (p=0.100 n=3+3) TransformRotate-32 2.65ns ± 0% 0.24ns ± 3% ~ (p=0.100 n=3+3) TransformTranslateMultiply-32 42.5ns ± 0% 12.9ns ± 0% ~ (p=0.100 n=3+3) TransformScaleMultiply-32 42.6ns ± 0% 12.9ns ± 0% ~ (p=0.100 n=3+3) TransformMultiply-32 42.2ns ± 0% 12.9ns ± 2% ~ (p=0.100 n=3+3) Signed-off-by: Egon Elbre <egonelbre@gmail.com>	2020-10-13 15:14:33 +02:00
