Hammad, The main bottleneck is usually the applications, not Kannel itself.
If your applications spent just a couple of seconds responding, at that rate messages will start to pile up, deplete your available sockets and finally sent your system(s) to a crawl. So, first of all, applications and gateway should be on separate servers. Depending on your application's design and load, you may consider a separate db server or even clustering for apps. Regarding Kannel, it's design is very efficient and nice on the CPU, so you won't need that dual-xeon with gazillion gigs of ram, but you should anyway put some decent hardware if you expect to manage hundreds of messages per second. I cannot give you specific specs, because there are too many variables that can affect the overcome, but as a rule of thumb: many cores or HT are always welcome, as well as memory. HD's not the main point of concern, since Kannel does a lot of it's stuff on memory, but if you use MySQL storage for DLR's or sqlbox, it may also play a role. You could use a separate DB here as well. As I've said before, your main point of concern is depletion of sockets because application's delays, so plan that part well and you'll be well on your path to succeed.
