With the release of go1.2rc3 last week I have now merged the autobench-next
branch into master in the autobench repository.
Go 1.2 is not expected to bring performance improvements of the same magnitude of Go 1.1, but moderate improvements are expected due to improvements in code generation, the runtime, the garbage collector, and the standard library.
If you would like to contribute a benchmark result from your own machine the instructions for doing so are included the README file.
