ea3ot, the time taken to update the baseline depends on how much data or programs you've added on since the baseline was last updated or created. The more "changes" there are the longer it will take. 30 min is about the time it takes me after about 2 months worth of use before updating the baseline. So judging from both our experiences, this seems normal.
The slow boot time issue is something that has plagued Rollback RX since i've been using it from v7 onwards. I cant speak for previous versions since i never used them. I've had three different comupters since then and each time Rollback was installed i've noticed a significant slow down in boot time over time. It seems the more snapshots that are taken results in a slower and slower boot time. It isnt an obvious slow down at first, but the accumilated effect definitely takes its toll.
An even bigger slow down is almost always noticed by me immediately after i Rollback to a snaphot. The first boot after I Rollback takes a lot longer than normally. Subsequent reboot seems to be quicker again but still not as quick as when Rollback is not installed. I say "ALMOST always" because every now and then i Rollback to a snapshot and my system seems to boot really quick. This lasts until i Rollback again and im back to slower boot times.
This is something i've learned to live with and have accepted as a compromise to having a fully protected system. I doubt that there's anything Horizon can do to completely eliminate this. They have done much to improve the situation but have still fallen short of completely resolving it.
Who knows, one day it may be worked out
