Dear Nanda, Have you checked for latency/retransmissions?
Try to setup max-pending-submits=100 in your smsc config.

I'm currently interested in delivered and undelivered messages only. Hence my dlr-mask is 3. Please suggest what I need to do in order to get the expected throughput? Besides, the problem I face here is that the speeds reduce gradually due to which there is no predictability in how long it will take to send all my messages. Is there anything in the data structure used for the dlr registration at the bearer box that causes the sluggishness when more and more dlrs are getting registered ?

Each dlr, including intermediate ones, counts -in terms of throughput- as one message. This is more noticeable when using modems. Also, as such the dlr handling consumes system resources. Therefore you should carefully select which dlrs you are interested in.

I was wondering if it were possible to have two sms boxes, one for sending the sms and another that the bearer box uses to redirect only the delivery reports. Please let me know. Thanks & Regards, Nanda From: Nanda Kumar P Sent: 24 April 2016 10:41 To: 'users@kannel.org' Subject: Create SMS box for handling dlrs Hi, I’m using one instance of bearer box and sms box each and I use kannel to send sms to the SMSC with delivery report parameters (dlr-mask & dlr-url) included in the send-sms url. I have no trouble functionality wise in sending the sms or getting the delivery. However, I do have a problem in the final throughput I see with and without delivery report. If I do not request for delivery report, the speeds are consistent at the rate of 300/sec which the throughput I have configured. However, when I use delivery reports, it starts with the expected throughput but gradually goes down to 25/sec or less. Any idea why this could be? I use kannel 1.4.4 Thanks & Regards, Nanda
