Hi guys, We have a head-scratcher. Whenever an admin creates a node, the rebuild takes over ten minutes. When they apply permissions to that node, rebuild takes over ten minutes. Installing or upgrading an addon can take over ten minutes. Basically whenever the permissions need rebuilding they take forever, and it can often mean that creating a new usergroup, adding users to that group, making a container and subfolders for that group, and then giving that group permissions to the container can take one of our staff well over three hours, and that's time they just don't have. We have two themes installed: UI.X Dark and XenBase (Zipped) (in addition to the XF default). We have three children for UI.X and one for Zipped. Total number of templates is thus: The forum itself zips along nicely. All other activity whizzes along. It's just this permissions rebuild that drags on way too long. Any ideas what can be done to chivvy it along?
