HA core is stuck in a reboot loop

Hi there… I find myself having a HA, which was stuck in a reboot loop. Now, since I have disabled some addons (nothing from HACS yet) and that I have moved the DB back from mariaDB to SQLite again, HA is extreeeeeeemely slow…

Can I find out, what is slowing down the system that much??

I have installed HA in a VM with HAOS - 32GB Ram and 4 i7 Cores.
Ram gets used nearly completely after a few days of running HA - CPU is at the moment at around 50%
