Title:
vmxnet3 LRO IPv6 performance issues (stalling TCP)
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
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
