autobench is a framework to compare the performance of Go 1.0 and Go 1.1.
autobench downloads and builds the latest Go 1.0 and Go 1.1 branches and runs a set of Go 1 benchmarks for comparison.
Useful targets are
make bench # runs all benchmarks, _once_
make go1 # runs bench/go1 benchmarks _once_
make runtime # runs bench/runtime benchmarks _once_
make http # runs bench/http benchmarks _once_
make clean # removes any previous benchmark results
make update # updates both branches to the latest revision, clears any benchmark results
You can optionally benchmark with gccgo instead of gc by either uncommenting the corresponding line in the Makefile or by setting TESTFLAGS to an appropriate value:
make TESTFLAGS=-compiler=gcc bench
There are several caveats to benchmarking last year's Go with Go 1.1.
- If you are benchmarking on an arm platform, remember that there was no automatic detection for GOARM, so you will have to set it yourself. See the GoARM wiki page for more details
Contributions and pull requests are always welcome. If you are submitting a pull request with benchmark data, please include the value of
hg id work/go.10
and
hg id work/go.11
in the suffix of your file (follow the examples) so we can trace which revision this benchmark was taken from. If you want to include commentry in your benchmark, comments should start with a #.
This package uses benchmark code from the Go project. Where otherwise unspecified this code is released into the public domain.
