Furthermore, DSL which stands for Digital Subscriber Line is a more efficient type of internet connection. It uses existing 2 wires that are with the telephone line so service is delivered simultaneously with wired telephone service; it won’t change the speed of the internet or the telephone like dial-up connection does. DSL connection speed ranges from 128 kbps to 9Mbps which is a lot faster than other connections like dial-up and ISDN.
The best internet connection is broadband. It is the most used form of Internet access because of its high access speeds. Broadband is defined as a high bandwidth connection to the Internet. Broadband is easier and faster to use than the traditional telephone and modem as information can be sent and downloaded much quicker.

PC Performance Factors
Browsers

Additionally, one browser could be faster than others at loading a single URL from the address bar.
Cache
Cache is a special high-speed mechanism. Cache can be either a reserved section of or an independent high-speed . Browser cache, also known as temporary internet files folder contains files from websites you have visited. The majority of web browsers maintain a cache of files.

- imposing controls on access to dubious material
- collecting useful statistics on web access
- providing cached resources even when origin server is down

Therefore, unique page views are commonly tracked to log the number of different visitors a website receives in a given time period. The more hits the website has the more traffic the website has which means it could slow down the performance of a website because lots of people are trying to access it at one time.
