Bryan Boreham 4dd3cbb4ab API client: make http reads more efficient (#976) ... Replace `io.ReadAll` with `bytes.Buffer.ReadFrom`. Both need to resize a buffer until they have finished reading; the former increases by 1.25x each time while the latter uses 2x. Also added a benchmark to demonstrate the benefit: name old time/op new time/op delta Client/4KB-8 35.9µs ± 4% 35.3µs ± 3% ~ (p=0.310 n=5+5) Client/50KB-8 83.1µs ± 8% 69.5µs ± 1% -16.37% (p=0.008 n=5+5) Client/1000KB-8 891µs ± 6% 750µs ± 0% -15.83% (p=0.016 n=5+4) Client/2000KB-8 1.74ms ± 2% 1.35ms ± 1% -22.72% (p=0.008 n=5+5) name old alloc/op new alloc/op delta Client/4KB-8 20.2kB ± 0% 20.4kB ± 0% +1.26% (p=0.008 n=5+5) Client/50KB-8 218kB ± 0% 136kB ± 0% -37.65% (p=0.008 n=5+5) Client/1000KB-8 5.88MB ± 0% 2.11MB ± 0% -64.10% (p=0.008 n=5+5) Client/2000KB-8 11.7MB ± 0% 4.2MB ± 0% -63.93% (p=0.008 n=5+5) name old allocs/op new allocs/op delta Client/4KB-8 75.0 ± 0% 72.0 ± 0% -4.00% (p=0.008 n=5+5) Client/50KB-8 109 ± 0% 98 ± 0% -10.09% (p=0.079 n=4+5) Client/1000KB-8 617 ± 0% 593 ± 0% -3.89% (p=0.008 n=5+5) Client/2000KB-8 1.13k ± 0% 1.09k ± 0% -3.27% (p=0.008 n=5+5) Signed-off-by: Bryan Boreham <bjboreham@gmail.com>		2022-01-25 11:16:10 +01:00
