we have been experiancing a problem on our campus. Many times, when you go to a website (say NYTimes.com for example) - it takes a long time to load the page (10-40 seconds sometimes). However, once the page is loaded, you can use the site perfectly normally. if you close down the browser and reopoen the page, it opens at a reasonable speed (though the next day it will often be slow again).
i know it is not a bandwidth issue - as our bandwidth is barely being touched relative to how much we have.
I would suspect slower hardware on the TMG server, but since everything seems good after the first time, i rule that out also.
could it be some type of cacheing thing, or scanning thing the first time a site is hit? how can i figure this out and resolve it?
we run tmg 2010 sp 2. version 7.0.9193.500
