Filip Gruszczyński 0b9607d1d6 encoding/gob: Speedup map decoding by reducing the allocations. ... The improvementis achieved in encoding/gob/decode.go decodeMap by allocate keyInstr and elemInstr only once and pass it to decodeIntoValue, instead of allocating a new instance on every loop cycle. name old time/op new time/op delta DecodeComplex128Slice-8 64.2µs ±10% 62.2µs ± 8% ~ (p=0.686 n=4+4) DecodeFloat64Slice-8 37.1µs ± 3% 36.5µs ± 5% ~ (p=0.343 n=4+4) DecodeInt32Slice-8 33.7µs ± 3% 32.7µs ± 4% ~ (p=0.200 n=4+4) DecodeStringSlice-8 59.7µs ± 5% 57.3µs ± 1% ~ (p=0.114 n=4+4) DecodeInterfaceSlice-8 543µs ± 7% 497µs ± 3% ~ (p=0.057 n=4+4) DecodeMap-8 3.78ms ± 8% 2.66ms ± 2% -29.69% (p=0.029 n=4+4) Updates #19525 Change-Id: Iec5fa4530de76f0a70da5de8a129a567b4aa096e Reviewed-on: https://go-review.googlesource.com/38317 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> Reviewed-by: Rob Pike <r@golang.org> Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>		2017-03-24 19:36:14 +00:00
