Understanding the Mechanism of Tools and Practicing Their Use
Techniques for increasing the speed of network access
- There are tools that enable users to speed up access to a network just by clicking the appropriate buttons. How can users increase the speed without upgrading access lines and PCs? Do these tools really make a difference?
This article examines their mechanism and presents techniques for enhancing the speed of access to the network.
Part 1: IP – The maximum size not subject to division, which is called the MTU size, allows for the greatest speed
Part 2: TCP – The default value of Windows should be set to a relatively small number, and the amount of received buffer space should be increased
Part 3: Application – The speed is increased by loading web pages before users access them and reducing the display time
Experiment: How effective is Jumbo Frame?
