In addition to what Trevor mentions, you may want to have a look at the uvconfig parameters, as well as the underlying OS kernel parameters, including file system settings, etc.
Also, file system fragmentation may be an issue, depending on how long it's been since it was looked at and addressed, especially if there is a lot of reading / writing going on with this file system. How is your /tmp space, and swap space? What flavor and versions of Linux, and UV? This is a process that your run when other users are not on the system, and possibly have these files open? You are correct to first suspect file sizing. Depending on how properly, or imporperly tuned they are, Dynamic files can introduce some overhead. Just a few ideas off top of the head... ----- Original Message ----- From: "Anthony Dzikiewicz" <[EMAIL PROTECTED]> To: <u2-users@listserver.u2ug.org> Sent: Sunday, February 13, 2005 7:11 PM Subject: [U2] Universe/Linux Performance Issue > I am experiencing some strange behavior on our Linux machine.
