What is MTU?
When you download a file, it is broken into many packets of data before it is sent over the World Wide Web to your computer (where it is then reassembled). The size of these packets is called your MTU value, or the Maximum Transfer Unit.
Setting your computer's MTU value too low would make downloading less efficient because a greater percentage of the packet is taken up by the packet header which contains a variety of information about the packet, source, and destination. However, setting the MTU too high can also decrease efficiency. Other computers on the Internet might not be able to handle MTU values of a certain size. If you set your computer's MTU value too high, some computers along the delivery path would be required to break these packets into smaller pieces before accepting them and passing them to the next computer. This "Stop. Break. Go." processing of packets can dramatically slow down data transfers.
It is usually best to select the settings Ascentive has researched by using the QuickOptimization panel in webROCKET 2001. However, expert users and experienced network engineers may make their own adjustments to the MTU value by using the Detailed Optimization panel in webROCKET 2001.
