Why OWA is very slow?

pc_remote--branch ==tunnel== head office--Exch_server
user_a at branch login to OWA and complain it takes long time (30-60") to load the page. It works lot faster in the past.
user_a can load other websites quickly ==> branch Internet connection is OK?
user_a can load OWA pages quickly (1-3") from head office ==> exch_server is OK?
There is no traffic shaping for the tunnel. No change to the tunnel setting.
user_a mailbox size is normal - 80MB.
Q#1. Any idea why user_a has such different speed?
Q#2. How can I 'dig' deeper to find out what 'slows' it down?
Thanks.

user_a has only 151 items in Inbox.
user is required to provide domain name, user name, and password. This is always the same in the past.
Why FBA takes more bandwidth?
user_a is using http for OWA, connecting not via vpn.
again there is no network change.

user_a can load OWA normally from another pc at branch.
I restart user_a's pc at branch and it can load OWA page normally too.
Q#3. Why user_a's pc has a problem with OWA but not other websites? I understand the pc may accumulate some 'garbage' which should affect all IE browsers, not just a specific one. Is it because OWA needs a lot more resources than a regular web page?

how to check the temp file for this page or the dns cache entry for the page?

I guess if dns file is incorrect, then it cannot load the OWA page at all. But it does load it correctly though extremely slow. Do you still think that it might be related to the dns file?
How can I verify if the temp files are corrupt?
