Hank
I appreciate the comment back. It helps explain the slow down and I agree with the comment on giving up views.
Thanks
Jon

>what I've seen with FileMon (http://www.sysinternals.com/Utilities/Filemon.html) is (with the view expanded to include all commands, not just the default setting commands) that there is a QuickRead done by the file server for each and every record of the table being used in the query. Not that these take long: by definition the QuickRead does not take that long; but when it is 400K or more of the critters, it can take a while. When there is only one user, locking contention is not an issue, and the QuickRead is not needed. This is an SMB thing: put the file on the same machine as the app, and with multiple users or not, the problem goes away.
