I should also note 2 things 1. that new hardware will help both these queries (mysql requires a filesort for this one, and thus it will be heavily affected by i/o load, which is usually pretty high on sourceware :( ) I'm still looking into what can be done in the meanwhile, of course. 2. Nobody in this thread has ever emailed me, or gcc@, before now, complaining about bugzilla UI/speed/etc You guys really should learn to complain more if you want things fixed. :)
