-Deprecated: benchcmp is deprecated in favor of benchstat: golang.org/x/perf/cmd/benchstat
-
-The benchcmp command displays performance changes between benchmarks.
-
-Benchcmp parses the output of two 'go test' benchmark runs,
-correlates the results per benchmark, and displays the deltas.
-
-To measure the performance impact of a change, use 'go test'
-to run benchmarks before and after the change:
-
- go test -run=NONE -bench=. ./... > old.txt
- # make changes
- go test -run=NONE -bench=. ./... > new.txt
-
-Then feed the benchmark results to benchcmp:
-
- benchcmp old.txt new.txt
-
-Benchcmp will summarize and display the performance changes,
-in a format like this:
-
- $ benchcmp old.txt new.txt
- benchmark old ns/op new ns/op delta
- BenchmarkConcat 523 68.6 -86.88%
-
- benchmark old allocs new allocs delta
- BenchmarkConcat 3 1 -66.67%
-
- benchmark old bytes new bytes delta
- BenchmarkConcat 80 48 -40.00%
