None of the setting were changed actually I looked at the default cupsd.conf.default file which is the original config before the update and it is exactly the same as the cupsd.conf current file. I have a ticket open with REDHAT this is definitly related to the rhn update and I also went through the
http://localhost:613 page but there are no rel performance settings. Im wondering if it has to do with the authentication setting each time a print job is generated.
