Before the beginning of this article, let's talk about the principle analysis of acceleration. If it is not right, please correct me!

Analysis of the principle of Internet acceleration:

In general, the default data transmission unit of TCP/IP accepts a buffer size of 576 bytes. If the size of this buffer is set to be large If there is an error in a certain TCP/IP packet data, then all packet contents in the entire data buffer will be lost and retransmitted; obviously, re-transmission will greatly affect the efficiency of ADSL transmission of data. To this end, set the appropriate buffer size to ensure that the efficiency of ADSL transmission data is always high, will have a direct impact on the ADSL transmission speed!

Detailed modification steps:

One, software up to people: lazy people are smart people

The place where you can drive does not walk, efficiency first, who remembers so much every day Registry key, come and go, open Rubik's Cube or Vista Optimizer.
