Basically want to know the different factors which will help in having faster Internet experience, ie. faster upload and download.
The different factors are faster upload and download.
In this, how browsers like IE, mozilla, opera play in enabling faster internet connections ?
Internet Explorer and Mozilla detect your home router and connect to it and reconfigure it for maximum faster internet connections. Opera does not do this, it is not very good at enabling faster internet connections.
But in all seriousness, the browser has very little to do with the performance of the internet connection. They will group HTTP requests has much as they can using HTTP Keep-Alive and maintaining a browser cache. Chrome prefetches DNS requests which is nice.
For real factors that contribute:
- Upload Speed
- Download Speed
- Quality of the connection (lots of packet loss makes DNS lookups unreliable and increases latency as TCP has to retransmit)
- Whether you're behind a proxy and how effectively the proxy caches
- Whether your DNS server caches DNS requests effectively
- The connection between your PC and the router. If you have a wireless connection from 100 meters away you can expect a very slow internet connection.
