Need technical assistance

[Marabekm]

Ok I am trying to help someone out that seems to be lagging a lot in multiplayer. I understand the speed=number setting in the config file may have something to do with it.

I have done some research, and it seems 25000 is a good number, with 40000 being the max? How do I determine what is best?
It seems hyperlobby default is 8000, so I know he needs to change it, but not to what.

Ok did some more research, and it appears that both the server and client need to have the same speed setting for there to be no lag. Is this correct? I am not a computer wiz so please tell me if I am going the wrong way here.

Also another question. How do I enable CRT. I looked in the config file but see nothing labeled CheckRunTime. I see options for Check server and Check client speeds. Is this the same as CRT?
