Unfortunetly, this causes even more read pauses from the source, when running rsync. I also tried cpio (-p mode) and cp -a, same pauses. When syncing, r4 seems to have about a 5 second pause, then a burst of seeks and writes. I also tried disabling clock throttling, no difference. I have a fast system. Two single core 2.6ghz opterons. CPU time during the pause after sync and before the writes doesn't seem to very high. I thought r4 might be cpu bound, but it doesn't seem to be. I'm not sure what's causing this pause. If i had more free time, i'd setup kernel profiling. -- Tom Vier <[EMAIL PROTECTED]> DSA Key ID 0x15741ECE
