To me it looks

or am I mistaken?
Yes, but you are not Marc Roos. Do you work on the same cluster or do
you observe the same problem?
No, but we recently also noticed that rebuilding one pool ("ssd")
influenced speed on other pools, which was unexpected.
In any case, here is a thread pointing to the crush
tree/rule
conversion I mentioned:

Thanks will check it out.
The tool is "crushtool reclassify" and is
recommended to use when upgrading from luminous to newer to convert crush rules to use
device classes.
Same here - thanks a lot for the pointers!
Cheers,
Nico
