Especially now that Simon has changed jobs, we need to try even harder to broaden the base of people who help with GHC. It would be amazing to have someone who was willing to: * Run nofib benchmarks regularly, and publish the results * Keep baseline figures for GHC 7.6, 7.4, etc so we can keep track of regressions * Investigate regressions to see where they come from; ideally propose fixes. * Extend nofib to contain more representative programs (as Johan is currently doing). That would help keep us on the straight and narrow. Any offers? It could be more than one person.
