Maybe it has nothing to do with a/the new realtime management, but with
spectre mitigation and stuff.

Phoronix listed all the kernel parameters to get rid of these
workarounds. I don't find the exact side anymore, but these are mainly
the parameters you have to add to your /etc/default/grub - only use
them, if you don't care about your system's security :D :

pti=off spectre_v2=off l1tf=off nospec_store_bypass_disable
no_stf_barrier


Greets!
