Re: Will Upgrading to V4R5 impact performance???

If you look at the history of EVERY computing system, upgrades of OS
features
have always required more memory, more disk, & more processor speed. Same
for pc (windoze & dos), unix, mac, mainframe, s34, s36, s38 & os/400. Why
the shock?
When I upgraded my B10 to a D10 in '90 or 91 - it took more memory & disk.
No big shock.
Also, as I pointed out in a very early post on this, your query problem may
have
been due to a missing ptf (which ibm documented in the psp since Oct 2000 as
a
definite fix to query performance).
IBM provides the tools to determine what you need "before" the upgrade, so
you
can make an informed decision.
