Comment 5 for bug 392204

I don't know if this is a different bug, but I'll stick it here.

Copy 3.7gb (DVD iso) to a USB hard disk formatted at FAT32 gives a consistent speed of circa 26Mb/s. Reformat to NTFS and repeat: the speed starts similarly, but dwindles down to 11Mb. It can't be fragmentation as the drive is just been formated. I originally had an issue when moving 8gb to an external HD, which started out at 19Mb/s, but ended up at 2Mb/s before the file copy had finished. Am using 9.10 release. I regularly copied stuff to my NTFS partitions under 9.04 and had no problems.

CPU usage very high on mount.ntfs, 70%+
