Emmanuel T Odeke 8333765b27 x/evm/keeper: save 24B with Go in-condition variable idiom (#828) ... * x/evm/keeper: save 24B with Go in-condition variable idiom The prior code doubly invoked (*ethereum/go-ethereum/core/types.Transaction).To() which is quite expensive, and firstly copies 20 bytes each time, then that gets rounded up to the proper size class/pointer alignment so on 64-bit machines 20B -> 24B. Isolating a benchmark for this code per issue #826 shows this saves quite a bit of bytes and some nano seconds which all count up towards the transactions per seconds being processed: ```shell $ benchstat before.txt after.txt name old time/op new time/op delta CopyAddr-8 38.4ns ± 3% 19.3ns ± 3% -49.66% (p=0.000 n=10+10) name old alloc/op new alloc/op delta CopyAddr-8 48.0B ± 0% 24.0B ± 0% -50.00% (p=0.000 n=10+10) name old allocs/op new allocs/op delta CopyAddr-8 2.00 ± 0% 1.00 ± 0% -50.00% (p=0.000 n=10+10) ``` Fixes #826 * changelog * lint * Revert stray changes that were used in testing * rm log Co-authored-by: Federico Kunze Küllmer <federico.kunze94@gmail.com>		2021-12-14 00:51:36 +01:00
