Hello,
I was wanting to ask a question before I upgrade.
What's the difference between 100MBPS and 1GBPS?
I own a Minecraft server and was wondering would their be a difference between the two? People keep complaining about lag (Australia) due to high ping and stuff. Would it make a difference?
Please reply with an answer.
Bandwidth will not impact latency unless your server is exhausting its bandwidth and causing packet loss and re-transmissions.
There is this pesky thing called the speed of light. It's a physical constant that we believe, and all evidence supports, that specifies the maximum possible rate at which information can be transmitted in a straight line. So consider the circumference of Earth: 40075km. That means that to communicate with someone exactly opposite of you on Earth's surface, information would need to travel 20037.5 kilometers. It takes light, in a vacuum, 0.06684 seconds to travel that distance, which translates to 66ms. Therefore, mathematically, it is impossible to communicate with someone over a land-line opposite the Earth with a one-way latency below 66ms.
For every 1000km distant a person is from you, it takes light about 3ms more time to carry information from one person to the other. If people are playing from other continents, often over 15,000 km from you, 45ms will be required just to transmit the information.
Now, factor in that there is no straight line between you and the other person, and the distance traveled is actually higher (by about 15-20%), that there is latency in processing data in routes/switches, and there are re-transmissions/packet loss, that light through fiber isn't quite as fast as light through a vacuum, and that the last few miles is copper wire, and that we measure "ping" as the time it takes to transmit a packet and receive a response, and latency on a global scale isn't a problem you can easily solve. This is why HFT traders want their servers within feet, inches if possible, of transaction servers, and why there are fiber routes being laid directly into Wall Street to shave off 5-10ms of latency (tens to hundreds of millions in investment).
In short: more bandwidth won't solve latency issues. If you're using more than the bandwidth currently available to you, it makes sense to upgrade. The only way to alleviate latency issues is by having servers in multiple locations. If you have 2 locations, opposite of each other on Earth, then no person on Earth can be more than 1/4 the Earth's circumference from one of them at all times, halving latency if you can correctly assign them to their nearest server. It scales pretty well if you can get servers all over the world, too.

The max downloadspeed I get is 11.2, according to the host.
The port speed is in megabits, download speeds are required in megabytes, you need to multiply the download speed by 8 to convert to megabits.
You asked a stupid question, don't be a smart arse and try to educate others. Your response also has ZERO relevance to what he was talking about, and I'm asking myself if you even understood his post. No shit he knows the difference between bits & bytes, in fact he probably knows more about IT networking than anyone else on this forum.Originally Posted by AeroMS
If you also had ANY idea what you're doing, you would have found the answer to your question in his post which pretty much summed it up.
The TLDR; of this thread - No, upgrading from 100MB to 1GB will not make the slightest difference, as you said so yourself you're only using less than 12MB of that bandwidth. When you have over 80MBPS of unused bandwidth, why would you POSSIBLY want to increase that gap tenfold? It will not affect ping in the slightest, the ONLY remedy for that is to have multiple servers in multiple locations (on a global scale, not one in your living room & one in your bedroom hurrrrr derrrrrr).
