Ok, I have an example query, that takes 4 sec in MonetDB. This is considered long, as Postgresql performs the same task in some 200 ms... I have used trace to get detailed information on what happens. But this output is really detailed : 2500 lines ! Here it is : http://pastebin.com/EmhERAeF For information, here the Pg explain plan, if that can be of any help http://explain.depesz.com/s/StM The point is that I don't know what to look for, so visualy parsing this output is quite hard :-) Any hint ? Thanks a lot, Franck
