Hi, I'm using kannel to send SMS to SMSC and in the send-sms url, I'm also using the dlr-mask as 3 (Delivered and undelivered) and providing a dlr-url callback for the same. I have set the throughput as 300/sec.
If I do not use the delivery report, the TPS is consistent and close to 300/sec. However, if I do use delivery report with the above said parameters, the TPS starts from 300 but gradually reduces to less than 25 per second. It would be great if someone can tell me what the reason for this could be. Thanks & Regards, Nanda
