Hi, My kannel speed of sending SMS is varying randomly. Over the past 12 months, I have observed very carefully about the factors affecting the speed. Let me share the important points with you:
- I have 20 different SMSC connections with one single operator - All connections have individual speed = 20 message/sec - My kannel config is following: BBOX <-> SQLBOX <-> SMSBOX <-> Application - Over different times, SMS bulk gets different overall processing speed. I checked network conditions as well as SMSC state, both have no issues. - Now for the same campaigns, I observe following difference in kannel monitoring window: When I am getting perfect speed, following line carries a lot of queued messages in SENT ONLY (kannel monitoring window): SMS: received 1427 (0 queued), sent 71000 (308 queued), store size -1 SMS: inbound (2.50,0.59,0.80) msg/sec, outbound (132.31,24.39,30.65) msg/sec Also in individual SMSC connection threads, I see SMS queued on every thread: *90101*[90101] SMPP:x.x.x.x:y/y:90101:90101 (online 3866s, rcvd: sms 40 / dlr 0, sent: sms 1874 / dlr 0, failed 0, queued 1200 msgs) *90102*[90102] SMPP:x.x.x.x:y/y:90102:90102 (online 3866s, rcvd: sms 35 / dlr 0, sent: sms 1943 / dlr 0, failed 0, queued 1148 msgs) *90103*[90103] SMPP:x.x.x.x:y/y:90103:90103 (online 3866s, rcvd: sms 28 / dlr 0, sent: sms 1936 / dlr 0, failed 0, queued 1320 msgs) ---------------------------------------------- On the contrary, when I am not getting good speed, following observations I can make on same window: SMS: received 149 (0 queued), sent 3702 (0 queued), store size -1 SMS: inbound (0.10,0.02,0.04) msg/sec, outbound (17.27,17.67,19.06) msg/sec *90101*[90101] SMPP:x.x.x.x:y/y:90101:90101 (online 4229s, rcvd: sms 0 / dlr 0, sent: sms 2050 / dlr 0, failed 0, queued 0 msgs) *90102*[90102] SMPP:x.x.x.x:y/y:90102:90102 (online 4229s, rcvd: sms 0 / dlr 0, sent: sms 2083 / dlr 0, failed 0, queued 0 msgs) *90103*[90103] SMPP:x.x.x.x:y/y:90103:90103 (online 4229s, rcvd: sms 0 / dlr 0, sent: sms 2112 / dlr 0, failed 0, queued 0 msgs) ----------------------------------------------- It seems that SQLBOX does not push the SMS to bearerbox with constant speed. Although more speed is available with SMSC connections, still I dont see kannel achieving high speed unless I see queued messages in SMSC connections. Can someone support my hypothesis? How to speed up SQLBOX's pushing of SMS to BBOX? Regards, Hamza
