I just want to put this out there its not a plugin or server issue, I just want to know how to calculate how many slots I can have for the hardware I own. The server is being hosted on my own network, the computer stats are below, we don't have a tone of plugins I know some people that pack their servers so full of plugins there is not a decent computer that can run the server. Anyhow below is an overview of what my hardware is if you want to help discuss your methods of calculating player slots feel free. I want to leave it open to people too and not so much focus on trying to find out the perfect about. Server Hardware: Processor: Intel(R) Core(TM) i7-6700 CPU @ 3.4GHz, 3401 MHz, 4 Core(s) Ram: DDR4 - 16GB Storage: HDD - 2TB Platform: Windows 10 Home - 64bit Network: Integrated LAN 10/100/1000 - Unlimited Data / High Speed & DDoS Protection. Upload Speed: 16.3 Mbps Download Speed: 174.4 Mbps Server: Using Bukkit GUI 2.0 for console We have 24 Plugins some are APIs and Libraries for plugins. Online Calculators: I don't trust what places like the one below as they only take in to consideration the RAM and Upload and download speed CPU is just important and I know that having DDR4 is better than DDR3 for ram so just stating the overall ram is giving you a very low estimate based on something that could potentially be better if it was calculated properly... http://canihostaminecraftserver.com/ I don't want to push the computer over the limit, however, I want to use a decent amount of the resources that I have at my disposal for my server. Feedback and Questions: If you are a server host what have you done to calculate your slots? Whats your computer hardware? How many plugins do you have on your server and do they require lots to run such as Dynmap? Do you host from your own network or server and if your own network what are your upload and download speeds?
