Unless you have spikes above 10 Mbps, you do not need a 100Mbps connection for only 1500GB of data transfer per month.

To clarify things, the 10Mbps is the instant measurement of how many bits per seconds can go through your server connection to the Internet. If you have enough traffic to saturate the 10 Mbps line, you can transfer, any given second, 10 million bits, or 10 / 8 = 1,250,000 bytes.

How does this translate into data transfer? Since there are 2,592,000 seconds in a 30-day month, you can transfer a maximum of 2,592,000 seconds x 1,250,000 bytes ~= 3,240 GB per 30-day month.

These are theoretical numbers. There is some overhead to take into account which varies, depending (among other things) on the quality of your bandwidth. With premium bandwidth, remove 5 to 10 %. With non-premium bandwidth, remove 20% or more.

How do you determine your needs? Quite simple from there. If your 1500GB monthly traffic is relatively constant (this is also called the "sustained bandwidth"), you certainly do not need a 100Mbps connection. That would be overkill and you would pay more without the need for it. On the other hand, if your traffic is such that one hour per day, you burst at 50 Mbps, while the remaining of the day, you consume 1 Mbps, your 10 Mbps connection will not handle the 50 Mbps bursts; it will be capped at 10 Mbps (the maximum speed of your connection). During burst periods, as you approach saturation on your 10 Mbps connection, you will start noticing that your sites are responding slower and slower. Some visitors will not be served at all. In that case, and if your site is mission critical, you might need to spend more money on a 100Mbps connection just to be able to serve your visitors during that one hour per day.

This is why it is critical to know your traffic, not only per month or per day, but also per hour. This knowledge helps you do the proper cost/benefit analysis.

To come back to your original question: "Does that term mbps deal with server speed? Seems when I upgraded, my site got slower. Is it because of the 10mbps?". The answer is actually no, because the term has nothing do do with the server speed itself; it has to do with the connection speed.

Be aware that there are many additional factors that can also impact the apparent speed of your sites: server hardware, configuration and optimization of the operating system and the different services like Apache, the use of scripts, the quality of such scripts, etc. For example, a poorly written script that creates a deadlock with bring your server down to a crawl, even during low traffic periods; such a situation happens more often than one might think.
