I recently moved a clients site over to a new hosting server, the domain is http://rodedwards.com/ Now for some reason my client is having an issue with the load time of his site. It was loading fine previously on his old host. This issue only occurs in Firefox for him and other browsers are fine. When viewing in Firefox it takes him around 20 seconds to connect to the site. Once loaded it is fine and other pages load normally in a couple of seconds, it's just that initial connection that takes ages for him. - I can't replicate the issue in Firefox or any other browsers. - All Pingdom and gt metrix performance tests indicate the site loads fine. - The site has a full set of speed optimisation techniques used, I disabled them temporarily to see if that was the issue but it had no effect. - He has tried a completely clear cache - His internet speed is fine and this only happens on this domain - He has tried Firefox in safe mode - He has tried a full Firefox reset - He has the latest version of Firefox - This happens on two of his computers in Firefox - He has tried setting network.http.keep-alive.timeout in about:config from 115 to 0 I have set the site up on different test domains to investigate and the following occur for my client: http://test1.rodedwards.com/ - Slow 20 seconds connection issue http://test2.rodedwards.com/ - Slow 20 seconds connection issue http://lsb15.nopixelleftbehind.co.uk/ - Loads normally in around 2-3 seconds http://lsb15.nopixelleftbehind.co.uk/ is actually on the same server as rodedwards.com and it the exact same site other than a new page that was added after the issue had already started. I'm stumped on this one and any assistance would be appreciated. Kind regards, Luke
