Hi! Just to give some feedback here: I do care for performance and any hint on how to improve it is very welcome. To make sure your suggestions are not forgotten please add a task in the bugtracker (eg. for the substr issue). Another thing that may help with your obviously very popular site: I redirect all feed traffic to feedburner (renaming feed.php, submit it to feedburner, use a rewrite to direct all traffic to them) this removes all flexibility from the feed but gives your server time to breathe and some nice statistics as well ;-) For performance I currently see two major bottlenecks: The feed. Harry you once submitted a summary renderer which is currently not used anywhere. Shouldn't we use it for the feed? The parsing engine. When a page can be delivered from the cache it is acceptable fast but if the thing has to be reparsed it can get slow (this is a problem with previewing eg.) We should see if can get some improvements there. Andi
