It's a Core2Duo 6400 so I think it's a bit high. when I cp that same file from ext3 to r4 I get pdflush at 50%CPU On Mon, Jul 14, 2008 at 4:40 PM, wrote:

Hello, Here is my timing on copying and removing 1 big file on a reiser4 partition. The Reiser4 partition is a separate Sata type disk.

Observation: The removal took some time. I was surprised about the time taken to remove the file. Glenn

# time cp /tmp/openSUSE-11.0-DVD-x86_64.iso .

real 1m37.936s user 0m0.048s sys 0m13.969s

# time rm openSUSE-11.0-DVD-x86_64.iso
