I've got the same issue, it works fine on windows, but on linux every 15-45 seconds a get a 2-5 seconds of lag. I'll make a video when I get some time.
I haven't been able to reproduce this issue, I do have a clock change in the next release that may help, please report back on any changes.
Nothing extracted yet.
The game is practically unplayable due to this. I'll join a server and my ping (I have net_graph 1) will go from a steady 40-50ish right upto 600-700 (often causing me to get kicked) for a few seconds then down to 40-50 again. This causes horrible banding etc. It's not my connection because I don't have this issue in Windows. It's not the server either I've tried 10-15 different servers and they all have this issue.
Screenshots - Take a look at net_graph in the bottom left of the game:
