Reading and writing a [32]byte key to a bufio.Reader/bufio.Writer can easily by done without allocating. Do so. It is slower; on my machine, it adds about 100ns per read/write. However, the overall request takes a minimum of several µs, and it cuts allocations meaningfully, so it is probably worth it. name old time/op new time/op delta SendRecv/msgsize=10-8 9.21µs ± 9% 9.08µs ± 8% ~ (p=0.250 n=15+15) SendRecv/msgsize=100-8 6.51µs ± 9% 6.60µs ± 7% ~ (p=0.259 n=15+13) SendRecv/msgsize=1000-8 7.24µs ±13% 7.61µs ±36% ~ (p=1.000 n=11+15) SendRecv/msgsize=10000-8 19.5µs ±15% 19.9µs ±25% ~ (p=0.890 n=14+15) name old speed new speed delta SendRecv/msgsize=10-8 1.09MB/s ± 8% 1.10MB/s ± 8% ~ (p=0.286 n=15+15) SendRecv/msgsize=100-8 15.4MB/s ± 8% 15.1MB/s ± 6% ~ (p=0.129 n=15+12) SendRecv/msgsize=1000-8 139MB/s ±15% 135MB/s ±28% ~ (p=1.000 n=11+15) SendRecv/msgsize=10000-8 516MB/s ±17% 506MB/s ±21% ~ (p=0.880 n=14+15) name old alloc/op new alloc/op delta SendRecv/msgsize=10-8 170B ± 1% 108B ± 1% -36.63% (p=0.000 n=15+15) SendRecv/msgsize=100-8 265B ± 1% 203B ± 1% -23.34% (p=0.000 n=15+15) SendRecv/msgsize=1000-8 1.18kB ± 1% 1.12kB ± 0% -5.31% (p=0.000 n=14+14) SendRecv/msgsize=10000-8 18.8kB ± 2% 18.8kB ± 2% ~ (p=0.443 n=12+12) name old allocs/op new allocs/op delta SendRecv/msgsize=10-8 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.000 n=15+15) SendRecv/msgsize=100-8 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.000 n=15+15) SendRecv/msgsize=1000-8 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.000 n=15+15) SendRecv/msgsize=10000-8 5.00 ± 0% 3.00 ± 0% -40.00% (p=0.000 n=13+14) Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com> |
