Benchmarks

These are benchmarks collected from the community used to measure the effects of changes to the Go core (compiler, runtime, and libraries). They should have the following properties:

• they matter; someone cares, perhaps in a dollars-and-cents way, that they run well
• they are go-gettable and don't require customized steps for building the benchmark
• they run under go test -bench ...
• they run relatively quickly, ideally a single "run" takes less than a second (there should perhaps be a separate set of longer-running benchmarks)
• their timings are not gratuitously noisy
• they run cleanly in a restricted environment, such as a Docker or rkt container
• they're not gratuitously redundant with other benchmarks already in the list; we don't need ten microbenchmarks of Go transcendental functions

Information for each benchmark includes (or should include):

• a short name for the benchmark
• the path to go get the benchmark
• a regexp for the benchmark suite excluding individual benchmarks that might be noisy, long-running, or redundant
• (ideally) a contact person for questions about the benchmarks
