Source Dedicated Server Help!

[BoguS]

I was messing around with dedicated servers the other day and after hours of trying, I got a source dedicated server up and running for 3rd Party Games.

I ran Gmod9 and BG2 mod, everything was fine until more then 6 people joined. As soon as the 7th player connected everything started to lag. Is there any way to solve this or can my comp/internet connection not handel more then 6 players?

My Comp Statz:

AMD athlon 64 3000+ (2.0ghz)
1 gb Ram
Nvidia 6600

I don't know my internet connection speed exactly, does anybody know a site where i can test upload/download speed? ( in europe). If i can fix this lag then i can host a ZP:S server, and there is no way im gonna play ZP:S with only 6 players...

It's probally your bandwith. I get the same problem on BB, my specs are over the roof, but my bandwith eats poop. I can only have 8 people max without them lagging on cable. But it is also because of al the zombies that they have to register to their computer then mine. So, yea. As with Zombie Panic, and it dosen't have bots, I can have a max of 11 playesr without any lag.
