I've logged a call with our support provider as since we rolled out the latest update we're consistently seeing our server running at 100% CPU. Even after shrinking log files etc it's still being absolutely swamped. It's a VM with 6 vCPUs running on a Xeon Silver 4210, however the chap I spoke to suggested this doesn't have the single core performance required for SIMS/SQL, and suggested upping the CPU count to 10! I think it's more likely we need some housekeeping/maintenance of the database, and for us it suspiciously became an issue after the Autumn 2021 release was deployed.
