How much has he minimized it by doing that? Is he running workgroup server? That's pretty cheap in my books. -----Original Message----- From: owner-informix-list@iiug.org [mailto:owner-informix-list@iiug.org] On Behalf Of Neil Truby Sent: Wednesday, February 23, 2005 5:05 PM To: informix-list@iiug.org Subject: Re: Single cpu vp woe ----- Original Message ----- From: "Art S.

However, the user wants to run on ONE physical cpu and has deliberately taken one out of his 2-way box. The reason is that he wishes to minimise his IBM Informix licence cost. It isn't delivering the performance he wants, but he wants to know if there's an inherent reason why. sending to informix-list

I'm in enough trouble already, without asking if the customer has pointy hair...
