Network Performance

Network performance is the speed at which your Internet access provider can carry the e-mail and other data you want to send. There are two aspects involved— the speed with which you can connect to the provider and the speed of the connection the provider has to the Internet. For obvious reasons, it’s important that your service provider has a very high speed connection to the Internet, lest your data sit idly on the system waiting to be dispatched to your customers or col-leagues.
The speed of a network connection is measured in bits per second (bps). Because a single character of data is composed of eight bits of information, a slow 2,400 bps connection, for example, would transmit 2,400 / 8 or 300 characters per second (in reality, it’s often less than that due to system overhead). This post is about 36,000 characters, for example, so with a 2,400 bps connection, it would take about 140 seconds, or just over two minutes, to transmit it to your machine. Contrast this with a 19,200 bps connection, which would require a transmission time of only 14 seconds. Internet service providers should have considerably faster connections to the Internet; a 56,000 bps connection between your service provider and its Internet connection is the minimum you should accept (at that speed this post could be transmitted in under 5 seconds).
