A really cool example of good debugging especially without the source.
Also a good reminder that the slow thing may not be what you think and if you aren’t profiling you don’t really know what’s going on.
And an even better reminder that typical “metrics” trying to assess developer value can be pretty meaningless. This is the kind of code change that would drastically improve everything but show up as a blip on some of the pathetic measurements out there, e.g. hardly any lines of code or whatever.
