Thanks for the suggestions. Acceleration is back on and DRI is off, oh, what a relief it is. I suspect my system has a more serious problem and that I am essentially tweaking the leaves while the roots are infected. I'm running an ICP hardware raid controler with raid level 5 and reiserfs. In addition to that, I run an rsync mirror to an IDE drive. I'm considering switching from raid 5 to 0 because I do see read problems and maybe some of the xruns occur during write. The read problems appear with Ardour while doing REW or F/FWD seeks and the messages are something about disk read access error. I've tried to google up some hints for performance tuning with hardware raid but haven't found any obvious suggestions. With the mirror running every 24 hours, I can probably afford to forgo the hardware redundancy. Maybe someone has some insites into hardware scsi raid performance. I'd be happy to investigate any suggestions. ron > -DR- > > __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security. So do we. http://promotions.yahoo.com/new_mail
