Comment 36 for bug 392204

I maybe have the same problem on 10.04.1 LTS

When moving files from NTFS partition to other (on different drive), I got a speed of 13747 bytes per second (13 KBps).
I see 50-90% CPU usage on one of the mount.ntfs processes, and uptime says:
 15:46:09 up 2:28, 2 users, load average: 2.07, 2.06, 1.94

I have Pentium 4 HT 3GHz on the machine, so there should be plenty of processing power.

On difference scenarios, I have seen 50 MB+ performance on the same drives using ntfs-3g.
It looks like it depends on the files, possibly file size.
