Well, at least I see people claiming >30% difference between different file systems, but no, I'm not shouting "bah, you'd better do this or I'll warez Oracle" :-) I have no idea how much you can improve over the "best" filesystems out there, but having two layers of journalling (both WAL _and_ FS journalling) on top of each other don't make all that much sense to me. :-) /* Steinar */ -- Homepage: http://www.sesse.net/ ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
