This is very strange. I have now set up a new server with apache, php, mysql, ispconfig. And I have uploaded a test website to it: http://www.ffatest.se/ The problem is that the site is slow in Chrome and Firefox when you are logged in. It looks like the site has finished loading but the browser continue to load for antoher 30 sek. This does not happend on my old server. I followed this guide when I set up the server: http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-courier-ispconfig-3-p3 Could it be some apache module that isn´t working as it should? The site is a Joomla 2.5.4 site.
