i was just thinking, if a high traffic forum with 20000 members, 500000 posts (almost 1 new post per min) and 300+ online users all time. the posts table is almost 230 mb in size, because of mysql lack of row locking, when a insert/update/delete action happens, the whole post table is locked, this really slow down the speed of browsing on a busy forum. shall i split the post table into two tables: active table which is used for normal forum use, archive table which stores old posts and only used for browsing/searching.

do inserting/updaing/deleting on a 20 mb post table is much faster than on a 200mb table, am i right? so is it nessary/possible to add a new feature for gforum, split posts table?

the backup table has same columns as active table, and by using mysql's "INSERT INTO ...... SELECT ..... FROM ...", i think it's not too difficult to move posts to another table.
