Joe Tsai 1f7479466e util/deephash: use sha256x (#5339) ... Switch deephash to use sha256x.Hash. We add sha256x.HashString to efficiently hash a string. It uses unsafe under the hood to convert a string to a []byte. We also modify sha256x.Hash to export the underlying hash.Hash for testing purposes so that we can intercept all hash.Hash calls. Performance: name old time/op new time/op delta Hash-24 19.8µs ± 1% 19.2µs ± 1% -3.01% (p=0.000 n=10+10) HashPacketFilter-24 2.61µs ± 0% 2.53µs ± 1% -3.01% (p=0.000 n=8+10) HashMapAcyclic-24 31.3µs ± 1% 29.8µs ± 0% -4.80% (p=0.000 n=10+9) TailcfgNode-24 1.83µs ± 1% 1.82µs ± 2% ~ (p=0.305 n=10+10) HashArray-24 344ns ± 2% 323ns ± 1% -6.02% (p=0.000 n=9+10) The performance gains is not as dramatic as sha256x over sha256 due to: 1. most of the hashing already occurring through the direct memory hashing logic, and 2. what does not go through direct memory hashing is slowed down by reflect.
