dlandon Posted May 9, 2016 Share Posted May 9, 2016 Turn off TSO on all NICs. Large Segment Offload (known as Transmit Segment Offload in Linux) was implemented to offload some network processing to the NIC. While good in theory, it appears to cause more problems than it solves. It was more appropriate in older systems with limited processing power, but can result in choppy video and audio in media streaming and gaming applications in modern systems. It should be defaulted off on all NICs. There is no reason for a user to turn it back on. Turn off TSO: ethtool -K ethX tso off Quote Link to comment
RobJ Posted May 18, 2016 Share Posted May 18, 2016 According to this page, generic segmentation should be off too, or it doesn't work. Anyone agree or disagree, and why? ethtool -K eth0 tso off ethtool -K eth0 gso off Quote Link to comment
dlandon Posted May 18, 2016 Author Share Posted May 18, 2016 It looks like you are correct. According to the article you reference, both must be off. Quote Link to comment
Squid Posted May 18, 2016 Share Posted May 18, 2016 Is this something that fix common problems should be checking for (under the "other" section). I don't know enough 'nix and/or networking to know anything about this Quote Link to comment

I don't know enough 'nix and/or networking to know anything about this Probably not. It doesn't seem to affect all users. I think it depends on a users setup and things like the network switch they use. I'm going to develop a plugin that will allow adjusting this and some other settings so users can experiment if changing settings can help with their issues. Quote Link to comment

dlandon Posted May 21, 2016 Author Share Posted May 21, 2016 I've developed a plugin that will permit users to work with this feature on their NIC(s). http://lime-technology.com/forum/index.php?topic=49233.0 Quote Link to comment
