I am working on a Joomla 3.3.0 website that has about 140 usergroups. However this causes the joomla to slow down, particularly when I am going to the sections of the website that needs to load the usergroups e.g. the global configuration and the configuration of each component. I also feel that module edit page loading, is taking a bit longer.
While waiting to load the page, Chrome throws a message that pages became unresponsive. If I click on the wait button, it will load them after a while.
Searching in Google, I found only a similar issue in a J2.5.
Has anyone any similar issue in recent Joomla versions?
Is this a known bug and how to deal with it?
