Troubleshooting Bandwidth through an ASA 5520 running 9.1

I have an ASA in Mexico City.  My measured bandwidth from a server at the site varies between 1-2 megabytes throughput.  Watching my ASA I don't see very much traffic or utlization through the Outside interface.  My internet service provider claims we have a 10 x 10 circuit that they have throughly tested.  I still only get 1-2 megabytes of throughput.  Are there any configurations on the ASA that might throttle bandwidth?  Also how do you test a circuit to make sure you are getting the bandwidth you pay for?

mtu Outside 1200

mtu OutsideSubInt 1200

Why did you change the MTu:

enable

config t

mtu Outside 1500

mtu OutsideSubInt 1500

That should put you back to what your ISP indicates you have.
