###… Qubes OS release
R4.3 rc1 and rc2
### Brief summary
After installing to an Ivy Bridge laptop, overall system performance is less than half of the same system running R4.2. The slowness is apparent both during and after installation.
### Steps to reproduce
Install R4.3 rc1 or rc2: Used defaults except de-selected Whonix to make install time shorter.
### Expected behavior
`time qvm-start personal` should complete in under 8 seconds (as per R4.2 start times).
### Actual behavior
`time qvm-start personal` takes 17-20 seconds to complete. Everything else, such as shell commands and Qubes admin UI, is sluggish.
There is also a separate but related issue with debian-13-xfce template where the Debian VMs idle for >30 sec during startup. For service VMs which have extra startup chores this pushes them over the 60sec timeout limit. This is remedied by starting the Debian template manually then shutting it down; the Debian template seems not to have completed its initial configuration making this one-time manual start necessary.
### Additional information
/proc/cpuinfo appears normal. I'm unable to probe processor speed settings with `xenpm` as it appears defunct. `dmesg` has only one 'error' line:
```
platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
```
