Emmanuel T Odeke 2ad5dca7a5 telemetry/log: sample reference for benchmarking harness ... Serves as a reference harness to get benchmarking started. Steps to run benchmark: $ go test -run=^$ -bench=. -count=10 After you grab the output, put the various comparisons into files before.txt and after.txt then edit those result names to have a common name e.g. s/BenchmarkLoggingNoExporter/BenchmarkIt/g s/BenchmarkNoTracingNoMetricsNoLogging/BenchmarkIt/g s/BenchmarkLoggingStdlib/BenchmarkIt/g Now run benchstat: * All compared $ benchstat no_log.txt tellog.txt stdlog.txt name \ time/op no_log.txt tellog.txt stdlog.txt It-8 289ns ± 2% 2780ns ± 3% 5100ns ± 3% name \ alloc/op no_log.txt tellog.txt stdlog.txt It-8 80.0B ± 0% 728.0B ± 0% 568.0B ± 0% name \ allocs/op no_log.txt tellog.txt stdlog.txt It-8 5.00 ± 0% 32.00 ± 0% 28.00 ± 0% * No logging vs telemetry log $ benchstat no_log.txt tellog.txt name old time/op new time/op delta It-8 289ns ± 2% 2780ns ± 3% +862.31% (p=0.000 n=10+9) name old alloc/op new alloc/op delta It-8 80.0B ± 0% 728.0B ± 0% +810.00% (p=0.000 n=10+10) name old allocs/op new allocs/op delta It-8 5.00 ± 0% 32.00 ± 0% +540.00% (p=0.000 n=10+10) * No logging vs Standard library "log" $ benchstat no_log.txt stdlog.txt name old time/op new time/op delta It-8 289ns ± 2% 5100ns ± 3% +1665.16% (p=0.000 n=10+9) name old alloc/op new alloc/op delta It-8 80.0B ± 0% 568.0B ± 0% +610.00% (p=0.000 n=10+10) name old allocs/op new allocs/op delta It-8 5.00 ± 0% 28.00 ± 0% +460.00% (p=0.000 n=10+10) * telemetry log vs Standard library "log" $ benchstat tellog.txt stdlog.txt name old time/op new time/op delta It-8 2.78µs ± 3% 5.10µs ± 3% +83.43% (p=0.000 n=9+9) name old alloc/op new alloc/op delta It-8 728B ± 0% 568B ± 0% -21.98% (p=0.000 n=10+10) name old allocs/op new allocs/op delta It-8 32.0 ± 0% 28.0 ± 0% -12.50% (p=0.000 n=10+10) Change-Id: I53b15e9da315615278c576f3a60108435417a9f7 Reviewed-on: https://go-review.googlesource.com/c/tools/+/212078 Run-TryBot: Emmanuel Odeke <emm.odeke@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Cottrell <iancottrell@google.com>		2019-12-19 18:19:13 +00:00
