Do any of you run an UO server? Can you help me a bit in details of it, how much bandwidth it is consuming and how much MB of RAM should be ok to run it? How must be the pings between to have a clean run? I think i am going to use it for 70-100 users.

Well I dont know much about the specs for a server but I can tell you that you can easily run 100-200 people with Pentium IV 3000MhZ and 1-2gb Ram.

The Ping should be less then 100 as after that the game gets really sticky. I also would like to note that the ping has a great effect in the gameplay. :)

Thanks for the input.
Our pings to USA is around 190-250 so i guess thats not a very suitable option eh.:)

Well yes. Its quite a competition between UO shards and its really hard to get players nowadays. If you get one his most likely a brick one which is banned in all the other shards ;)
