I'm on Ubuntu 18.04.3 LTS, kernel is "5.0.0-25-generic".
Some pages (I've only hit one so far, it's the browser fingerprint tester at https://panopticlick.eff.org/) cause high utilization in Palemoon. It maxes out 100% on one "CPU" and the browser becomes very slow to respond to anything, while everything else on the mcahine seems fine.
'top' shows me that all that utilization is confined to one hyperthread - I've git a 6 core system, in top that shows as 12 "CPUs", and all the utilization is on one of those "CPUs".
Is there any way to spread the load?
The system is a Powerspec, using an Asrock H310M-HDV/M.2 motherboard. 16GB of RAM.
