Hi users I am not sure what is going. Kannel seems to be running quite slowly. Before we submit a batch of SMS to Kannel we parse the status page for the queue size. From the status page I am using:
*SMS: received 489 (0 queued), sent 0 (0 queued), store size -1* It seemed to me that the *sent 0 (0 queued)* meant that Kannel had already forwarded on all the messages that we had sent it and there is nothing in the internal queues. We have been submitting batches of messages to it and back off when the queue size is too big. How ever when I check our logs the queue size is always 0. We are submitting at most 50 a second to two different smsc. We have dealt with these SMSCs before and know that they can handle the volume. A lot of the messages which we have submitted are taking an incredibly long time to be sent or so it would seem. On the DLR callback from Kannel I record the time. The difference between the ack and the deliver is almost immediate. This leads me to believe that it is perhaps Kannel that is slow. I had a look at top and the box seems quite idle. I also record when we submitted the message. The difference between when we submit to Kannel and we get the first ACK from the SMSC is up to an hour now. I have not yet converted the Kannel DLR tables to MyISAM. That is still on my to do list. There appears to be over 50k in the DLR storage. I don't think that that has anything to do with it but I thought it might be worth mentioning. I had a look in the logs for bearerbox. There seem to be 1 or 2 errors every minute regarding Invalid Destination address but I don't think that would lead to slow performance. Smsbox logs have no errors or warnings. I would appreciate any thoughts, guidance and/or advice. Regards,
