Hello list, the company I work for is using Kannel 1.4.3 on CentOS 6 as SMS gateway between our application servers and an SMSC. We have developed a multithreaded application that sends HTTP GET requests to our internal Kannel proxy. Everything goes smooth up to 5 application threads. The problem is that when the number of threads goes beyond 5, the responsiveness of Kannel seems to fall down to the point that it doesn't even accept more requests. I couldn't figure out where the problem is, nor which parameters adjust to widen the number of possible concurrent requests.
Are there any limitations on the HTTP side of the gateway? Shouldn't Kannel accept requests at max speed, queue them and then deliver to the SMSC according to the accept rate of the SMSC itself? I've read through the documentation multiple times but I couldn't find any solutions yet. Thanks a lot for your support! Cheers, Fabio
