Only one way to find out...I'm telling you, migrating to a totally different setting where it acts like you "own" a server is an entirely different experience. The main thing that takes forever is the database migration. Our database is getting hefty...
Finally, and I ran two simultaneous backups and a gzip all at the same time as I was using the "thanks/groans" stuff and we never even hit 2% of the CPU... Hopefully this will work for a while.
