the chat barely uses less than 60mb of ram, as seen in this picture:
http://puu.sh/1jGaF. the used category is how much ram is used.
plus our CPU is a server-grade quad core Xeon:
http://puu.sh/1jGbI.
RAM and CPU has nothing to do with bandwidth usage, so unless the RAM and CPU are extremely low (can't handle what the server is running) it wouldn't affect how much lag there is (or isn't). As far as 256mb ram and the Xeon CPU, those I find are typical of most web servers, and most chat scripts and game servers can run quite well with those specs.
Lag is inevitable for something like chat scripts or game servers, but having two running at the same time will reduce available bandwidth too much, depending on the amount of bandwith there is. The more, the more connections that the server can accept before lagging. It has nothing to do with CPU or RAM specs as I think those can run both a game server and chat fine. And I don't think openTTD is really going to use much in the way of resources except for bandwidth either.
Now, the thing that concerns me the most about having an openTTD server is.. how many people are going to use it? The more people that play on a game server, the less bandwidth that's available as each player has to connect to the web server to send/receive game data.
As for a wiki, it can't be considered a "program" really, so I don't think it would be much of a problem unless we had hundreds of people using it on a regular basis. Also, as for site growth, this is another issue.
Can I ask, how much bandwidth is the chat using now? And how much is your host giving you in total? I should also add that it's important to factor in a user basis, chat uses plenty of bandwidth from a person's network also. So depending on how far away they are from the chat server, the higher the ping will be.
edit: duncan has 500gb bandwidth on his server. 500gb is more than enough to run a game server and chat at the same time (unless we're taking something like maybe BF3 or minecraft with huge world and 20 players). But openttd doesn't come close to that.
