Increasing Speed of Internet Using MTU settings in xp

Increasing Speed of Internet Using mtu settings in Windows XP:
Maximum Transmission Unit (MTU) refers to the size (in bytes) of the largest packet that a given layer of a communications protocol can pass onwards. MTU parameters usually appear in association with a communications interface. The MTU may be fixed by standards (as is the case with Ethernet) or decided at connect time (as is usually the case with point-to-point serial links). A higher MTU brings higher bandwidth efficiency.

A higher MTU brings higher bandwidth efficiency.

The default and maximum PPPoE MTU size is 1,480 bytes. With some Internet service providers (ISPs), you may have to reduce the MTU size of a PPPoE connection to a value between 1,400 and 1,480 (for example, to 1,454). Do not set an MTU size smaller than 1,400.
Modify the MTU size requires registry editing in windows xp
