Performance on 46C
Hi, Volker.Thanks for the explanation (and thanks a million for the call!). I
hadn't realised that the CPW rating must be divided by the number of
CPU's to determine the CPU capability per user. Knowing that now,
and the fact that the S30 is outdated technology explains the poor
responses on that machine after the upgrade.
Thanks again, I really appreciate it!
Regards,
Des.
