Sergiu, We will try that and get back to you.
On another note, we were also having some slowness problems: the object editing screen takes around 1 and a half minutes to upload on pages where XWiki.Rights or XWiki.GlobalRights are located. Taking them out fixes the problem. The access rights editing page is also slower, especially loading the groups, albeit not as slow as object editing. I suspect that LDAP might have something to do with it, though I am not sure. Our XWiki has exploded and now hosts a huge group of people (thanks to you :) ) who are all mapped by LDAP, which may slow the site down if the LDAP authentication mechanism calls LDAP everytime a page is loaded, or object edited. Am I on the right track here, or is this problem attributed to something else?

Any insight would be greatly appreciated. You should try to: - increase the memory available to XWiki (attachments take up LOTS of memory, this is a known problem which will be fixed at some time) - increase the max_allowed_packet setting for mysql (assuming you're using mysql) -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
