Well, I've stated it many times before and will do so again since we have so
many new members on the list.  The new sizer works, but many companies do not
fill it out in a realistic fashion.  The old sizer _NEVER_ worked, IMO, and I
have always recommended a processor jump in concert with doubling the
suggested memory and DASD from what the old sizer recommended.  When moving to
V6 from a V4 release, you will experience the same "CASE crunch" that MAPICS
users on older versions experience when moving to XA.  In trying to be all
things to all people, CASE tools of any manufacture inherently open more files
and require more code than the older "hand written" versions did.  BPCS is
even worse, as it incorporates so much SQL.

If you're not on V4R3 and running SMP across multiple processors, you're at a
performance disadvantage with V6.  By the time you make it to this list, it's
too late to tell you to get it written into your contract that you get a free
upgrade if your sizing information is correct but you still experience
performance problems.  Too bad...
