mtu used for branch offices and gre tunnels

Hello gurus.

I think I have a problem in my network. Branch offices are connected with a ipsec  gre tunnels. It's necessary to avoid fragmentation down MSS or MTU size on any lan segment, branch office or main site, to increase http web pages response?

Any help will be apreciated!

 

Thanks a lot for your help.
