Toot

I'm working on a tool to bisect through a git history to find performance changes to a given benchmark.

Unlike a traditional git bisect, which looks for a boolean change, we want to find points at which a value has a sharp jump.

For comparison above is a graph with 50 points vs below measuring 300 points at a regular interval (it has a slightly different X axis... I made a mistake). I think the old version looks better but the new version was way faster to generate and it more precisely narrows down the specific commit(s) which caused a change (rather than an interval, which I'd then have to bisect).
