Been struggling with a performance issue for weeks, been writing a search engine (or sorts) for internal company use only. Discovered the locations that are being indexed contain a directory used for back up purposes that contain archives of everything inside it.

Wrote a means to exclude these directories, performance improves up to 1600% (top end, sadly, not across the board) feel freaking awesome.

Boss acts like I've just pull Atlantis off the floor with my teeth.

It was a two line change, I wish the really difficult tasks were treated this way and not with "oh it shouldn't take you long!"
