https://www.fedex.com/shipping/shipEntryAction.do?method=doEntry&locale=en_us&urlparams=us&sType=F once they logon. Both of these sites are said to be painfully slow to logon and refresh. I have observed this first hand via my remote access software. The same sites are much faster when accessed from the corporate office. I have contacted support at the first site https://login.avidxchange.net and they said things are fine at their end and I need to check for Spyware on these computers. I scanned with MBAM and came up with nothing.
The computers are Windows 7 Professional SP1 + Security Updates. They load set is the same for these computers at the branch office and the computers at the corporate HQ (both IE8) except for a postage mailing app called Dazzle. Other computers (both Windows 7 SP1 + Security Updates and Windows XP) at the same site are said to be much faster at loading these web sites.
We route all traffic from the branch site through our firewall here at the corporate HQ and then out to the internet. What is the best way to tackle this problem to identify the culprit for the slowdown of these two sites?
