If your IO speed with local disk is slow too then I think slow network speed is just a consequence of a bug like this one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1264707 Title: IO limit 1.2 MB/s for 32bit ubuntu (PAE, 32 Gb RAM) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1264707/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

yeah, sorry, I ment lightdm. killing gui/unity fixes the problem. Local disk IO is not slow like in your cases, but I still think issues are related.

setting kernel parameter mem=16384M did not help (was set via grub GRUB_CMDLINE_LINUX=mem=16384mb) killing lightgm resolves the problem and speed jumps to 12mb/s .
