[Bug 1275853] Re: Poor upload ethernet speed in kernel 3.11.0-15-generic and Atheros AR8151 NIC

  Thread Previous • Date Previous • • Thread Next 
That is good news.  That means the bug is fixed upstream.  Can you also
test the latest upstream stable 3.11 kernel, which is 3.11.10.3?  It can
be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.10.3-saucy/

If the bug is fixed in 3.11.10.3, then the fix will make it into Saucy
when those updates are applied to the Saucy kernel.

Title:
  Poor upload ethernet speed in kernel 3.11.0-15-generic and Atheros
  AR8151 NIC

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  I am experiencing performance problems with ethernet upload since I
  upgraded Ubuntu 13.10 to the kernel version 3.11.0-15-generic. I have
  a gigabit lan and when uploading to the NAS (Ubuntu server) the speed
  is very low - approx 130megabites/s.

  This is not present in the previous kernel 3.11.0-12-generic. I tested
  this repeatedly several times and also I did a fresh install of the
  ubuntu 13.10 - still the same behavior.  I tested with copying large
  files to mounted nfs share and also with iperf.

  Interesting is that after booting Ubuntu 13.10 with kernel
  3.11.0-15-generic, the upload speed is fine for a while, then it drops
  down and remains low.

  See the iperf log (first run immediatelly after boot is fine - upload
  speed is 932Mbits/s, then second run 439Mbits/s and then only approx
  130Mbits/s ). Note that when testing with kernel 3.11.0-12-generic
  iperf will give allways ~930Mbits/s.
