What is the general rule for minecraft server hosting?

I want to use my current file/back-up server to host a minecraft server for a group of mates.

Its specs are

E2160 - 2x1.8Ghz
6GB DDR2 800mhz
4x1.5TB HDD (Raid 10)

On virgin 50Mbit, with 5Mbit upload.

Roughly, how many can I host to without it being laggy?

Cheers
 
how many do you need to host? I guess you would hit mem issues before anything else. I run one on a VM on an E8400 (1 vCPU) and 2GB and apparently it runs fine
 
The big RAM hit is per server instance - the per player load is relatively small. Its been awhile since I hosted any minecraft servers and the game has a fair bit more content since but I was finding it would hit about 500-600MB RAM useage on a large map with 10-12 players active.

Upload was the key thing for not being laggy as it would upload a compressed version of the current map to each new player on joining so if your link was saturated sending that data it would get laggy for everyone connected (again this might be more opptimised these days) but personally I'd say 2MBit/s upload is the absolutely minimum and you want closer to 10Mbit for a busy server - most of the time it won't be using more than a couple of KB/s per player but the burst on new connections is killer.

Depends on your system resources obviously but..

I *think* the biggest variable for RAM usage is how big the map gets, some people like to run for miles and miles.. the further the map extends the more RAM and resources the server will need.

I'm not sure how to do this but i know there is a way to pre-render terrain, so you can say for example.. pre-generate the map at say 20000x20000 in size. That way, when players are on your server and exploring most of the work will already have been done, taking the load off your CPU and giving you an idea of RAM usage.

That sounds promising, that could be a good thing to do. Thanks
 
I've been running a Minecraft server just fine on an old Core2Duo E6600 and 2GB of RAM. Had half a dozen connected to it at a time without too many issues and RAM is certainly the limiting factor. I only had the server set to use 600MB or so.
