They seem to be. : Next check the speed of the disks with something like iozone. IOZONE tells me: JAZ: 1.5MB/s write, 5.2MB/s read Fireball: 1.4MB/s write, 2.7MB/s read Disks are both 4500 rpm. The JAZ is 12ms seek and the Fireball is 10.5ms seek time. These disks could easily be much faster :-) However, async, noatime mounting seems to be about the best thing I can do for the build. I have about a half dozen builds done now, and want to do one or two more. I'll post the summary when I finish. Warner
