Justin Nuß 5f859ba83d time: Use AppendFormat in Marshal[Text|JSON] ... The current implementations of MarshalJSON and MarshalText use time.Format which returns a string (converted from a byte slice), only to convert it back to a byte slice. Avoid the conversion (and thus an allocation) by directly appending the formatted time to a preallocated byte slice, using the new AppendFormat function, introduced in golang.org/cl/1760. This reduces the allocations done in Marshal[Text|JSON] by 50%. benchmark old ns/op new ns/op delta BenchmarkMarshalJSON 626 507 -19.01% BenchmarkMarshalText 598 511 -14.55% benchmark old allocs new allocs delta BenchmarkMarshalJSON 2 1 -50.00% BenchmarkMarshalText 2 1 -50.00% benchmark old bytes new bytes delta BenchmarkMarshalJSON 96 48 -50.00% BenchmarkMarshalText 96 48 -50.00% Fixes #11025 Change-Id: I468f78d075a6ecc1cdc839df7fb407fbc6ff2e70 Reviewed-on: https://go-review.googlesource.com/10555 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>		2015-08-22 11:31:58 +00:00
