Use go4.org/mem for memory safety. A slight performance hit, but a huge performance win for clients who start with a []byte. The perf hit is due largely to the MapHash call, which adds ~25ns. That is necessary to keep the fast path allocation-free. name old time/op new time/op delta GoParse3339/Z-8 281ns ± 1% 283ns ± 2% ~ (p=0.366 n=9+9) GoParse3339/TZ-8 509ns ± 0% 510ns ± 1% ~ (p=0.059 n=9+9) GoParse3339InLocation-8 330ns ± 1% 330ns ± 0% ~ (p=0.802 n=10+6) Parse3339/Z-8 69.3ns ± 1% 74.4ns ± 1% +7.45% (p=0.000 n=9+10) Parse3339/TZ-8 110ns ± 1% 140ns ± 3% +27.42% (p=0.000 n=9+10) ParseInt-8 8.20ns ± 1% 8.17ns ± 1% ~ (p=0.452 n=9+9) name old alloc/op new alloc/op delta GoParse3339/Z-8 0.00B 0.00B ~ (all equal) GoParse3339/TZ-8 160B ± 0% 160B ± 0% ~ (all equal) GoParse3339InLocation-8 0.00B 0.00B ~ (all equal) Parse3339/Z-8 0.00B 0.00B ~ (all equal) Parse3339/TZ-8 0.00B 0.00B ~ (all equal) name old allocs/op new allocs/op delta GoParse3339/Z-8 0.00 0.00 ~ (all equal) GoParse3339/TZ-8 3.00 ± 0% 3.00 ± 0% ~ (all equal) GoParse3339InLocation-8 0.00 0.00 ~ (all equal) Parse3339/Z-8 0.00 0.00 ~ (all equal) Parse3339/TZ-8 0.00 0.00 ~ (all equal) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com> |
