Michael, I just upgraded my box to 5.8, and, for my surprise the CPU usage was
worst... I was able to use 100% of the cpu0 and the latency started to increase.
Here is my dmesg output:

5.5 is no longer supported. Upgrade sequentially (5.5 -> 5.6, 5.6 ->
5.7, 5.7 -> 5.8) and see if that fixes it. I've seen a huge network
performance improvement over that series of upgrades.
Also, if the problem persists, please include a dmesg with your next
email.
Thanks,
Michael
