A server requires very little resources, a $5 VPS from Digital Ocean can easily run a few hundred players. The main bottlenecks are usually (in order): bandwidth, CPU, uplink, memory and diskspace. For more hosts, please check out our Server Hosts page.
Bandwidth and network usage
While this greatly depends on scripts and sync rates, generally 100 players will use 5 mbit up and 1 mbit down. This means a server with 100 players consistently throughout the entire month uses 2 TB of bandwidth.
This again greatly depends on scripts and sync rates, a server with a few light scripts will use about 10% of an i5 CPU at 3.10 GHz. Most servers however will be running huge scripts so it entirely depends on the scripts and their optimisation.
Memory and disk usage
This entirely depends upon your scripts and log file. The server without any scripts or log file uses around 30 MB of disk space and 40 MB of RAM.
We ran the final beta test on a dedicated server with the following specifications:
- Intel(R) Core(TM) i5-3570S CPU
- 4 cores at 3.10 GHz
- 8 GB of RAM
- 2x 1 TB at 7200 rpm in software RAID 1
- 100 mbit full-duplex
Please note that most of this was not necessary, on average the server used:
- 1-2 full cores
- 400 MB of memory
- 250 MB of disk space
- 50 mbit up, 10 mbit down
