Sir,
They(SMSC Engrs) are saying that we can send out as much as 500sms/sec and our target rate is only 20-30sms/sec. Any ideas how to improve this rate, the queue we had keeps on getting bigger specially when we do broadcasting where sending out rate at worst goes to 2-3sms/sec. I badly need to improve this performance but i don't know where to start. :(
I've already used test_cimd2 to test kannel performance, everything works well and traffic rate is around more than a 100/sec. But when I connect to SMSC traffic rate slows down to:
SMS: inbound 0.07 msg/sec, outbound 1.11 msg/sec
But looking at access.log, message processing is @ 3-5sms/sec rate. Thanks in advance
ok, unfortunatly I'm not familiar with Nokia's CIMD protocol. But I guess that CIMD2 does so called "flow-mode", which means it passes an MT and waits to receive a ACK from SMSC. When ACK is received, it sends the next MT messages, and so on.
You may drop us a snipp from the bearerbox.log where the CIMD2 connection trace is shown, just to verify.
So IMO, this either a) up to the SMSC not ACK'ing as fast as they claim they could, or b) your IP connection uplink is that narrow bandwith'ed that the IP traffic (along the CIMD2 PDUs) is consuming to much of it and hence things get slow.
