Makes you wonder if these recent Linux kernel mitigations for Meltdown, Spectre and the rest could be the culprit, or at least in part. They are known to cause performance issues with some software, it may be worth turning off the patches at boot or using a clean kernel to compare. I may try booting without them over the weekend and try noting any differences, although I'm not getting any noticeable slowdowns anyway so not sure what good it would do on my setup.
