Add to the mix indexes and triggers. They can both add to the time needed to update just one record.

You might be able to address the first at your desk, the latter may require a purchase order. How old is your hardware? We recently upgraded to a virtual server and just using more current technology hard drives we doubled all of our disk I/O from what we had 5 or 6 years ago. CPU speed increased as well, but that was not as suprising. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Dave Laansma Sent: Monday, April 30, 2012 6:01 PM To: U2 Users List Subject: Re: [U2] READU vs READ Yes, using SELECT and READNEXT. These are sizable records. The logic is very straight forward, just updating several multi-valued fields in each record (month end). 500,000 have been updated and I'm 2:45:00 into the process. _____________________________________________________________________________ Scanned by IBM Email Security Management Services powered by MessageLabs.
