Hello Bayo,

now, the load-capacity of Kannel acting as WAP GW can be as follows:

Linux 1x CPU Xeon 3.4G, 2GB RAM handles arround 200-250 req concurrent
Linux 8x CPU Xeon MP 2.7G, 4 GB RAM handles arround 750-800 req concurrent

now these are local benchmark testing.

When using in a real-work production environment you will have for the first 
example arround 180-200 concurrent connections handling.

Kannel is designed to spread the load across wapboxes, so each wapbox handles a 
queue of req. Using 2 wapbox means: un-blocking requests that fly throu the 
system.... and so on

Now using more and more wapboxes has a draw-back. At bearerbox we need to route 
the WDP datagrams to the corret wapbox.

Usually optimum is something between 2,3,4 wapboxes. Not more. I suggest trying 2.

If you need further support, please let me know.
