Bug Description

[Impact]
The throughput measured by iperf3 is around 70% of 1Gbps (Intel I219-LM
[8086:15b7])
I219 is a rather cheap NIC and it impacts its throughput if TSO(TCP
segmentation offload) is enabled.

[Fix]
Disable TSO on NIC and move this task back to CPU fixes this issue.
The impact of CPU loading is little to none.
On target machine with Xeon(R) CPU E3-1505L v6 @ 2.20GHz(4c8t), the CPU
usage of iperf3 increases from 1% to 4%

[Verify]
Origin
[ ID] Interval Transfer Bandwidth Retr
[ 4] 0.00-10.00 sec 918 MBytes 770 Mbits/sec 0 sender
[ 4] 0.00-10.00 sec 916 MBytes 769 Mbits/sec receiver

[ 4] 0.00-10.00 sec 1.09 GBytes 934 Mbits/sec receiver

[Regression Potential]
Low, disable TSO on Ethernet chip will move the TCP segmentation task
to CPU. This increase CPU loading a little bit, and should not introduce
any regression.

=============================

Testing with iperf3 send speed is only 750mbps while receive speed is normal - 940mbps.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1802691

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Changed in linux (Ubuntu):
status: New → Incomplete

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".

Thanks in advance.

I dis not upgrade. I did a clean install. Unfortumately I probbly won't be trying a mainline kernel because it seems that it's too complicated to remove.

Simas (pechius) wrote :

I have to ckarify. The problem is NOT with receive/download speed, but with SEND. SEND speed on Ubuntu machine are too low. Iperf is a bit backwards, but I confirmed it by checking my windows pc traffic.

I installed the mainline kernel 4.19.2 and the problem didn't go away, so the problem hasn't been addressed.

I've just confirmed the problem again by trying to transfer a file between Windows 10 and Ubuntu 18.04.1 via samba. Upload speed from Windoes to Ubuntu is 110-115MB/S, while download from Ubuntu to Windows is only 88-90MB/S.

There seems to be another possibly related or unrelated issue. If SAME DIRECTION transfer is initiated from the Ubuntu machine, the download speed to Ubuntu is actually 85MB/s vs 112MB/S if it's initiated from Windows.. that seems to be really weird, but I'm not alone:

Simas (pechius) wrote :

While I was waiting for a fix, I've just noticed a new problem.. Now the transfer speed became very inconsistent. For the first few seconds when I'm sending TO Ubuntu I get 110MBs (as expected), but then speed drops to 50, 30, 20 and keeps going up and down for the rest of the files transfer. Very disappointing.

I also encountered network performance degradation on my server, however I'm not running Ubuntu but Debian with a self-compiled kernel. With bisecting the kernel, I could track this issue down to this commit between 4.14.2 and 4.14.3:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0f478f25d50cb6464678284a13f514fefc16e271

I was tempted to undo this change in my kernel, however this change works around a bug in the I219 adapter and I didn't want to end up with an unstable system. Related to this bug I read about TCP segmentation offload and changed tso and gso values with ethtool. Eventually "ethtool -K enp0s31f6 tso" off did the trick for me and network performance is back to normal. You might have to change the name of enp0s31f6 to the name of your Ethernet adapter or play with on/off values for tso and gso.

In order to persist this setting after a reboot, I created a udev rule that calls ethtool, maybe this option works for you as well.

I'm also experiencing this issue and I'm trying to fix this for days now. The send speed caps out at about 700 Mbps. I'm not seeing any hangs or connection losses though. I'm eager to find a solution for this, as I have to move 50 TB over that server.

What I've tried:
- Kernels: 4.15.58, 4.15.60 from bionic-proposed, 5.3rc6
- ethtool:
"ethool -K enp0s31f6 tso off gso off" doesn't do anything
ethtool doens't even have an option for tso, because "ethtool -k enp0s31f6 | grep tso " doesn't return anything
"ethtool -k enp0s31f6 | grep gso" returns
tx-gso-robust: off [fixed]
tx-gso-partial: off [fixed]
tso is probably already off?
- installed latest driver from intel: no change

I would be really thankful I've anyone has a solution for this.
