I have a Joomla website that is very slow to load, often timing out with the message "The connection was reset".
The site is: http://www.i-nth.com
The website performance tool at http://tools.pingdom.com/fpt/ tells me that it usually takes at least 10 seconds (and sometimes 30 seconds) before the first response is received from the server, and then things seem to complete within a few seconds. I've enabled compression of the CSS and Javascript, which reduced the page size from 1100 kB to 735 kB. I've tried disabling various features (such as the Flash slide show, Twitter feed, quote thing in the top right-hand corner, etc), but it makes little difference to the load time.
So, I'm wondering if the problem is my website (perhaps a slow script, or similar), or is the problem with my host's server?
Any suggestions?
