Since 1MB was faster than 1GB for some reason,
because it has to reserve 1GB of RAM. If there is not enough, it uses swap. You can see that watching 'top'.
It's a plain workstation with 4 cores and 4Gb RAM - anyway, I think Greg misread my numbers - using bs=1M, the 20Gb was copied in 27 minutes, with bs=1000M it took only 17M, so the bigger blocksize did help. -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
