[Kernel-packages] [Bug 1605494] Re: vmxnet3 LRO IPv6 performance issues (stalling TCP)

2017-04-13 Thread Kleber Sacilotto de Souza

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
trusty' to 'verification-done-trusty'. If the problem still exists,
change the tag 'verification-needed-trusty' to 'verification-failed-
trusty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1605494] Re: vmxnet3 LRO IPv6 performance issues (stalling TCP)

2017-03-10 Thread Freaky

Installed it and speed is on par with IPv4 now.

Thanks for the quick response, much appreciated.

One question though, will the manual installation of this version get in
the way of kernel updates or will it pick them up again if a newer one
than 113 comes out?

Have a nice weekend!

[Kernel-packages] [Bug 1605494] Re: vmxnet3 LRO IPv6 performance issues (stalling TCP)

2017-03-10 Thread Freaky

Made an error in my previous comment, it's the other way around between
16.04 and 12.04.

Downloading on a 16.04 *from* a 12.04 goes fine (mostly TX for the
12.04). Downloading on 12.04 from 16.04 (or anything else) is horrible
(mostly RX for 12.04).

Any incoming IPv6 on the 12.04's is rather bad and has a lot of drops.

  We have performance problems with TCP over IPv6 with SSH/SCP and HTTP traffic 
on Linux guest virtual machines running on VMware ESXi (6.0u2). We are running 
Ubuntu 12.04.5 LTS, 14.04.3 LTS and soon 16.04.1 LTS.
  If we upload (large) files with these protocols the performance go's down to 
200kb/s.
  With IPv4, we have a much higher performance.

[Kernel-packages] [Bug 1605494] Re: vmxnet3 LRO IPv6 performance issues (stalling TCP)

2017-03-10 Thread Freaky

Hi,

having similar issues with 12.04 (with both trusty and precise kernels).

Don't see any fixes for the trusty kernel. Tried adding trusty, but
launchpad gives an oops when I try to.

We have several webservers with IPv6 directly attached to internet. 2
12.04's both running with trusty kernel now and 2 16.04's.

16.04 <-> 16.04 consistently around 110MB/s (gigabit limit)
Downloading on 16.04 from the 12.04 machines is horrible. Connections die, huge 
drops in performance (sub 1MB/s)
12 <-> 12.04 same as above.

Please add fix to trusty kernel as well.

Kind regards,

Hi Stefan and Tim,

Is this patch also available for Ubuntu 12.04 LTS and 14.04 LTS?
The fix in -proposed works in Ubuntu 16.04.1.

Kind Regards,

[Kernel-packages] [Bug 1605494] Re: vmxnet3 LRO IPv6 performance issues (stalling TCP)

2016-08-16 Thread Stefan Bader

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  vmxnet3 LRO IPv6 performance issues (stalling TCP)

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Fix Committed
Status in linux source package in Yakkety:
  Fix Released

Bug description:
  We have performance problems with TCP over IPv6 with SSH/SCP and HTTP traffic 
on Linux guest virtual machines running on VMware ESXi (6.0u2). We are running 
Ubuntu 12.04.5 LTS, 14.04.3 LTS and soon 16.04.1 LTS.
  If we upload (large) files with these protocols the performance go's down to 
200kb/s.
  With IPv4, we have a much higher performance.

  This is a known issue in the vmxnet3 driver that is fixed upstream on the 
21th of April:
  "This is due to check sum handling issue in the vmxnet3 driver. Fix is on 
  the kernel tree." http://comments.gmane.org/gmane.linux.network/401727
