I have been researching SSL Offloading and I understand the why and the how - but when? I cannot find any documentation to use as support for making this change. So far the best I have found is an environment with "thousands" of users should use SSL Offloading. Has ExBPA been updated to recommend at a certain point?
I have TMG servers in a DMZ, F5 LB and a 3 node CAS array for approx. 26,000 users. Servers were specced above standard in 2012. Exchange 2010 SP2 RU7 on Server 2008 R2 SP1.
