These are benchmarks collected from the community used to measure the effects of changes to the Go core (compiler, runtime, garbage collector, 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

**These benchmarks change over time, and that is okay.** Their intended use is for performance testing of proposed changes; is the geometric mean better, were any benchmarks made substantially worse?

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

There is a [benchmark runner](https://github.com/dr2chase/bent) that automates downloading, building, and running these benchmarks under various (user-defined) configurations.  Benchmarking noise on Linux can be somewhat reduced with [perflock](https://github.com/aclements/perflock).

A few have been proposed but have so far failed to make the cut (for fetch, build, or noise problems):
