Notch has stated a number of times that the actuall size of the map doesn't matter since only parts of it are loaded at any one time. The only time the size of a map would cause lag is if there where a large number of players all in different chunks. This would cause the server to have to load an active chunk for each one. Basically its a similar instancing system (in principle, not necessarily implementation) to what WoW does.

Main causes of the lag would probably be to do with things like fluid physics calculation or a large amount of logic calculations; e.g. large amounts of flowing water, magma, fire or possibly large amounts of redstone logic or Minecart related processing.

Actually that might be the problem; Minecarts keep chunks active... So all those unattended minecarts at boosters and stations etc will be keeping chunks active that wouldn't normally be active causing an unusual amount of work for the server, i.e lag.

Edit: also according to the bug list, boats cause a lot of lag :S

I sent a mail requesting to be on the whitelist like the OP said. I think I sent it to the correct place but if not can I be white listed anyway?

Start of my new minecart bridge

To whoever put a sign by my track saying it should connect to grand central: I like it leaving from spawn, it's convenient

All I have to say on the subject is that I like pie.

I think so too.

Guess it's a good time for food then

I'll build a giant fortress on the great hills in the middle of the railroad going to Moria, but I should find a good theme for it.

DWARVES!

It's officially working again and the glass road tubey thing is officially awesome.

Thanks! I have to lay track in it yet and before that finish cobbling the floor. I also need to finish the bit where it meets the spawn
