Emmanuel T Odeke	3e92899bd9	internal/libs/protoio: optimize MarshalDelimited by plain byteslice allocations+sync.Pool (#7325 ) Noticed in profiles that invoking *VoteSignBytes always created a bytes.Buffer, then discarded it inside protoio.MarshalDelimited. I dug further and examined the call paths and noticed that we unconditionally create the bytes.Buffer, even though we might have proto messages (in the common case) that implement MarshalTo([]byte), and invoked varintWriter. Instead by inlining this case, we skip a bunch of allocations and CPU cycles, which then reflects properly on all calling functions. Here are the benchmark results: ```shell $ benchstat before.txt after.txt name old time/op new time/op delta types.VoteSignBytes-8 705ns ± 3% 573ns ± 6% -18.74% (p=0.000 n=18+20) types.CommitVoteSignBytes-8 8.15µs ± 9% 6.81µs ± 4% -16.51% (p=0.000 n=20+19) protoio.MarshalDelimitedWithMarshalTo-8 788ns ± 8% 772ns ± 3% -2.01% (p=0.050 n=20+20) protoio.MarshalDelimitedNoMarshalTo-8 989ns ± 4% 845ns ± 2% -14.51% (p=0.000 n=20+18) name old alloc/op new alloc/op delta types.VoteSignBytes-8 792B ± 0% 600B ± 0% -24.24% (p=0.000 n=20+20) types.CommitVoteSignBytes-8 9.52kB ± 0% 7.60kB ± 0% -20.17% (p=0.000 n=20+20) protoio.MarshalDelimitedNoMarshalTo-8 808B ± 0% 440B ± 0% -45.54% (p=0.000 n=20+20) name old allocs/op new allocs/op delta types.VoteSignBytes-8 13.0 ± 0% 10.0 ± 0% -23.08% (p=0.000 n=20+20) types.CommitVoteSignBytes-8 140 ± 0% 110 ± 0% -21.43% (p=0.000 n=20+20) protoio.MarshalDelimitedNoMarshalTo-8 10.0 ± 0% 7.0 ± 0% -30.00% (p=0.000 n=20+20) ``` Thanks to Tharsis who tasked me to help them increase TPS and who are keen on improving Tendermint and efficiency.	3 years ago
