Wonder what effect timing in Qubes.

I don’t know.
And attempting gaining Qubes developer attention also seems futile given the abundance of other unresolved Qubes issues:
https://www.whonix.org/wiki/Dev/Qubes#Issues
Therefore not even suggesting opening a ticket. Maybe related:

#… ## Qubes OS release
R4.1
### Brief summary
The Xen hypervisor has performance problems on certain compute-intensive workloads
### Steps to reproduce
See @fepitre for details
### Expected behavior
Same (or almost same) performance as bare hardware
### Actual behavior
Less performance than bare hardware
First, somehow a test or program would have to be written to reproduce this in a Qubes Debian VM. Then even if reported against Qubes, it might actually be a Xen issue that is difficult to fix and/or hardware dependent.
In short: I doubt we can reach this level of perfection.
