slow access https sites

[jjohnsoncantell]

Greetings,

 

Im running forefront tmg 2010 and have a problem when accessing https sites. When i try to access an https site such as hotmail or my hosted owa i get hit with quite a long delay before the site is accessible. For example, going to hotmail.co.uk, i have to wait 10-15 seconds before i can click anything and another 20-30 seconds after logging in before i can do anything. My owa on a hosted system gives me up to a 10 second delay when first connecting too. I only get this delay with https sites. The same happens on the initial loading up facebook.

 

Any ideas what may be causing this?

James
