Clean install of Gutsy final. copy a 350mb avi file at times is slow but can also start transferring at 120+mbs, then within seconds it drops to around 50mbs which by this time it has finished copying. I have noted it going as slow as 14mbs from 122mbs.
Transferring a large avi file of 900mb always starts at about 11mbs, drops as low as 6mbs but increases to 20mbs as the copying nears 100% complete.

copying from an ext usb hdd stays at about 25mbs from start to finish, i believe this would be about max due to the usb limited bandwidth.
