To clear out some space for testing on sda, I copied a 12G file from sda to sdb, in 2m54s, or about 68 MB/sec one way. I also noticed a major difference in the vmstat output. Both the blocks in and blocks out showed much larger numbers. Rarely did the wait times go above 20%, and I don't think I saw it go over 30%. I'm now diffing them, and seeing wait times in the low 30% range, and lots of blocks in. The diff took 2m51.849s to read 24 G. -- Charles Curley /"\ ASCII Ribbon Campaign Looking for fine software \ / Respect for open standards and/or writing?
