OK, my bad. I did not do thorough research, just enough to satisfy my curiosity. If ext3 does well and safely, then more power to 'em. Anyway, sorry, what I wrote was not intended to be flame bait, just blowing off a little steam. I'll go crawl back under my rock now. However, I stand by the assertion that a slow, certain default is better than a fast, uncertain one. That async was ever the Linux default is troubling (to me), and I've got plenty other reasons to prefer BSD over Linux (which is why I didn't do thorough research in the first place -- no interest at all in migrating, even if there's a database speed boost). -- Greg Barniskis, Computer Systems Integrator South Central Library System (SCLS) Library Interchange Network (LINK) <gregb at scls.lib.wi.us>, (608) 266-6348
