We have tried it in a real production environment, and our experience is with an old dual-processor Pentium III 500 MHz system with only 256 MB RAM. We managed to get Kannel to handle well in excess of 200 messages per second inbound at peak without breaking a sweat. The telcos we were connected to were surprised to see that there was no queue for our service, even though it was very active. That meant Kannel was receiving and forwarding messages to our SMS services at that rate, which is truly impressive. (Well, the other half of this story is that the database backend that we were using could not withstand this blasting of transactions... :( *sigh*)
