Super slow performance

I have the exact same behavior. It is so slow unlocking that I just changed the Auto-lock time to be 4 hours vs 10 minutes like it was previously set to. This effectively makes me less secure.

v8 in general seems pretty buggy. I have multiple vaults and it's not uncommon (at least once a week) that one locks on me while the other stays unlocked. When this first happened I panicked because I thought I had lost passwords. Hopefully they are aware of and working on these issues. At this point I would not consider v8 to be an upgrade.
