When you say UBB has no CPU issues - are they bearing in mind the fact that the CGI is called about twice as often without the static HTML? It would need be twice as efficient as V5 to have no increase in CPU.
Secondly - what about CGI memory - my shared host automatically chops processes that use over 8 MB of RAM. My shared server only has 128 MB. But UBB 5 works fine. I just have this feeling UBB 6 will not.
