Confirmed some of the speedup by compressing enwik9 three times. Best time goes from 60.35s (elapsed) to 58.27s, with low variance, and that includes time doing I/O. |
As long as matchAt does not return a pointer, escape analysis determines that the matches can stay on the stack. This works in Go 1.17, too. name old speed new speed delta Encoder_EncodeAllSimple/best-8 13.5MB/s ± 3% 15.3MB/s ± 2% +13.35% (p=0.000 n=19+19) Encoder_EncodeAllSimple4K/best-8 11.9MB/s ± 1% 12.9MB/s ± 0% +8.38% (p=0.000 n=19+17) name old alloc/op new alloc/op delta Encoder_EncodeAllSimple/best-8 16.0B ± 0% 14.0B ± 0% -12.50% (p=0.000 n=17+20) Encoder_EncodeAllSimple4K/best-8 1.00B ± 0% 1.00B ± 0% ~ (all equal)

I added another commit with a further speedup and updated the totals in the PR description. |
