Date: 10/26/1999 Author: TR Jeffrey << previous in thread กค next >> Hi, I have some first hand experience supporting that many users (1000+) on a Linux box. It scales VERY well right on up. Your only limitation is the amount of ram you put in the box. Our rule of thumb was1.5MB of ram per connection. Now, some quick calculations would show that that adds up to 1.5GB of ram, but we're only using 1GB; you have to consider that not everyone will be hitting the box at the same time. To loosen up some bottlenecks, slap in another NIC card or two and load balance between them. Your other consideration should be what your back bone has on it and what kind of switches/routers you have. If you can V-Lan down to the port and send traffic to a specific card on the box, that would be the best way. Then watch your traffic through your network with some monitoring software to increase the bandwith where needed. Hope this helps!
