Is this a new SMPP Gateway that you set up after upgrading Diafaan SMS Server or did the send speed suddenly go down after the upgrade?

45 to 50 messages per seconds is not bad for Diafaan SMS Server, it is possible to get a higher throughput but only if all conditions and settings are optimal. The routing settings in Diafaan SMS Server also have a lot of influence on the throughput, the more complicated the message routing is, the slower the send speed will be.

Can you try to set the 'MaxMessagesPerSecond' property to '0', the 'MaxMessagesPerMinute' property to '9000', the 'MaximumBatchSize' property to '1000' or higher and the 'AsyncModeWindowSize' property also to '1000' or higher? These settings should result in the maximum throughput you can achieve on your server with Diafaan SMS Server.

Hello Henk,

Thanks for the quick turn around. We have done the settings as instructed by you, still we are seeing that sometimes there are 1 or 2 messages but still they wait in the Send Queue and after 4 to 5 secs time they are been sent to the SMPP Gateway.

We are not able to understand and rectify the issue please help as the SMPP gateway provider are saying that we are not pushing them the messages in the required per sec speed that is the reason they are queuing up at our end. Please let us know if you need any further details to investigate this.

Thanks
Sarfaraz

Hello Sarfaraz,

There were no changes in the functionality of the SMPP Gateway in recent versions of Diafaan SMS Server that would explain a slower performance and I don't think that the new version is the cause of the slower message sending. Did you change anything in the settings of the SMPP Gateway or did you create a new gateway after installing the new version?

Make sure that the 'MaximumBatchSize' property is set to at least 5 times the number of messages per second, in your case 750 or higher, otherwise the SMPP Gateway will not get the messages from the message queue fast enough.

Another point is that if you set the 'MaxMessagesPerSecond' to a value higher than '0', the 'MaxMessagesPerMinute' setting is not used. The difference beween the two settings is that 'MaxMessagesPerSecond' keeps the amount of messages that are sent below the set value, in your situation it means that no more than 150 messages will be sent every second (and probably less). The 'MaxMessagesPerMinute' setting means that in an optimal situation exactly the desired number of messages will be sent every minute.

Hello Henk,

We are using the new version 3.2.0.0 in this version we are facing the issue of slow message sending to the SMPP Gateway. The gateway has given us a speed to submit 150 messages per second. We have set the MaximumBatchSize 150. Asyncwindowsize 150. MaxMessagesPerMinute 9000 and MaxMessagesPerSec 150. Still we are not getting 150 we are only getting upto 45 to 50.

Please let us know where we are going wrong with the setting as there were no issue in the earlier version everything was working fine.

Thanks in advance.
Have a great day!!!
