I have upgrading a 2010 intranet website and after that the site is loaded sometime fast and others not.
I have enabled the developer dashboard, checking the logs, checking the servers , apply latest cumulative updates but unable to realize the issue.
The farm has 4 servers , 2 located in one building and the reset are located in another building far around 3 kilometer. Each building has 1 web front-end and another application server box.
could any one help me to trace the issue?
