Evgenii Stratonikov	665e5807bc	[#188] transformer: Allow to provide size hint ... For big objects with known size we can optimize allocation patterns by providing size hint. As with any hint, it does not affect transformer functionality: slices with capacity > MaxSize are never allocated. ``` goos: linux goarch: amd64 pkg: git.frostfs.info/TrueCloudLab/frostfs-sdk-go/object/transformer cpu: 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz │ out │ │ sec/op │ Transformer/small/no_size_hint-8 65.44µ ± 3% Transformer/small/no_size_hint,_with_buffer-8 64.24µ ± 5% Transformer/small/with_size_hint,_with_buffer-8 58.70µ ± 5% Transformer/big/no_size_hint-8 367.8m ± 3% Transformer/big/no_size_hint,_with_buffer-8 562.7m ± 0% Transformer/big/with_size_hint,_with_buffer-8 385.6m ± 7% geomean 5.197m │ out │ │ B/op │ Transformer/small/no_size_hint-8 13.40Ki ± 0% Transformer/small/no_size_hint,_with_buffer-8 13.40Ki ± 0% Transformer/small/with_size_hint,_with_buffer-8 13.39Ki ± 0% Transformer/big/no_size_hint-8 288.0Mi ± 0% Transformer/big/no_size_hint,_with_buffer-8 1.390Gi ± 0% Transformer/big/with_size_hint,_with_buffer-8 288.0Mi ± 0% geomean 2.533Mi │ out │ │ allocs/op │ Transformer/small/no_size_hint-8 92.00 ± 0% Transformer/small/no_size_hint,_with_buffer-8 92.00 ± 0% Transformer/small/with_size_hint,_with_buffer-8 92.00 ± 0% Transformer/big/no_size_hint-8 546.5 ± 0% Transformer/big/no_size_hint,_with_buffer-8 607.5 ± 0% Transformer/big/with_size_hint,_with_buffer-8 545.5 ± 0% geomean 228.1 ``` Signed-off-by: Evgenii Stratonikov <e.stratonikov@yadro.com>	2023-10-30 12:13:04 +00:00
