First in this post let’s understand what we are talking about. The next post will talk about how to improve performance. And finally, a post to talk about the “why this matters” and how this affects which web-conferencing software platform to use for your online event.

Download
Download is a measure of how fast your connection delivers content to your computer or local area network. This is the important number to test – it will determine how many or how smoothly different web-conferencing functions will work (audio, downloading content, video, presenter video, etc.)

Upload
Upload is the measure of how fast content is delivered from your computer or local area network to others on the Internet. This is important to note if you are a presenter who is uploading content to your web-conferencing platform. Especially when trying to upload those last-minute presentations or changes!

Kbps
Kbps transfer rate = kilobit per second transfer rate. There are 8 bits in a byte, so we would divide kbps by 8 to get KB/sec transfer rate.

Transfer Rate

Transfer rate is speed at which data can be transmitted between devices. This is sometimes referred to as throughput. As files to download become increasingly larger, the highest data transfer rate is most desirable. Finally, I like to note that the simplest and most easily available method to measure your connection speed to the Internet is to simply download a large file and see what is the transfer rate reported in your standard download progress dialog box.

Latency
In a network, latency, a synonym for delay, is an expression of how much time it takes for a packet of data to get from one designated point to another. In some usages, latency is measured by sending a packet that is returned to the sender and the round-trip time is considered the latency. Low latency is extremely important for businesses and power-users. It’s not all about bandwidth! Conventional wisdom says that increasing bandwidth will lead to improved performance. In fact, the transmission control protocol (TCP) limits the number of concurrent bytes transmitted, regardless of the size of the transmission pipe and effects latency.
