My Friend Rakes Called me and said

“My web page hosted in my new hosting provider is not loading fast like my previous provider. It is slow and sluggish to load. They are cheating me. I am gonna withdraw my hosting service from them”

This is my lesson to him.

In Worl Wide Wep (WWW) i.e Internet, Very critical parametr is Speed. Like a 350 kmph F1 Cars, Higher the speed you get through your ISP more you go crazy, More is the wastage. Can i call it as a “E-Wastage” in real it is a Resource wastage. Mostly internet service providers use a term called concurrency, even though you subscribed for 5 Mbps,It is not dedicated across a globe to every hop. Because they understand the Technology and limitations behind Internet speed.

A Network connection is controlled by TCP (Transmit Control Protocol), Data transfer to the same is limited to TCP window size of 64kBytes. Time taken to reach your hosting provider, and back (latency) limits no of windows that can be tranfered in a second, and hence your throughput.

For example: A latency of 200 Milli second to your hosting server will limit your single session throughput or bandwidth to 2560 kbps. Since the across the globe internet connectivity is through submarine cables latency of this magnitude is normal between continents. Even though your speed availability is 5 mbps, you can not establish 5 mbps connection to every host. Bandwidths are shared, physical mediums are share. After all we share this sphere called Globe, Why not Internet.

Internet Speed available to you from Points across the globe can be measured by running a speed test. It will create virtual TCP sessions and report you the reading. so many websites offer this service, one such web site is http://speedtest.net/

Latency or time taken to reach your domain or Hosting provider can be identified by doing a simple ping from your PC/Server/Device. command “ping yourdomain.com” in linux “ping yourdomain.com -c 3”

Certainly internet speed isn’t a Rocket Science. Happy Surfing!
