The load_avg is being read for every request, but it's only actually used if the tile is old or missing. 87% of requests that reach apache on tile.osm.org are for current tiles. Skip load_avg in that case. Saves about 1.2% Apache CPU time (a few micros per tile). You can view, comment on, or merge this pull request online at:
