I have two different computers, one a desktop, the other a laptop. Both have different network controllers in them (one Qualcomm Atheros, other Realtek). Both using the included driver.
Both computers have Xubuntu 13.04 x64 currently, but the results are reproducible on 13.10 (with Kernel 3.10 and 3.11 daily) and 12.04.2, and Lubuntu 13.04. The results are also the same on the desktop if I use a compiled Realtek driver (8168 I think).
If I try restoring files from a backup computer, the transfer speed at a most goes around 50MB/sec, on both machines. Network information is reporting 1000 Mb/s.
The same computers under Windows can easily get 70-90MB/s transfer speeds while restoring backups.
Just to be clear, I'm dragging some folders from a Samba share on another computer, to my desktop and laptop (not at the same time) using Xubuntu's file manager, Thunar.
Any idea what's up?
