I checked again, and I have to take back my previous statement. "pci=routeirq" does not seem to speed up file transfers for my system. (The KDE4 file transfer progress window seems to provide a not very conclusive average speed value)
The reason I posted in this bug report is that I believe this actually is a kernel issue. I did several measurements copying big files (1.4 GiB Video) with Dolphin, Konqueror, on the command line using "dd" and using cp like follows: "time (cp 1.4GiB-testfile.mkv /media/disk; sync)". The speed varies between 3MiB/sec and 8 MiB/s. On another PC with OpenSuse installed, I actually get much higher average transfer rates, between 12 MiB/s and 15 MiB/s. On the same PC booting MS Windows, I also get around 14 MiB/s. -- file transfers on USB disk are very slow https://bugs.launchpad.net/bugs/197762 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
