Hello Sarfaraz,

The best settings in Diafaan SMS Server depends on the SMPP service provider and it is difficult to provide an exact answer. In general you should set the "AsyncModeWindowSize" to the maximum value that is allowed by your SMPP provider and the "MaximumBatchSize" to 5 times the maximum speed per second, for 80 SMS per second it should be approx. 400. Then set the "MaxMessagesPerMinute" property to the maximum speed that your SMPP server accepts, in this case 4800 for 80 SMS per second.

You can use 4 Transmitter/Receiver binds when you use 4 SMPP gateways. With the basic edition of Diafaan SMS Server you can use up to 4 gateways. If you want to set the maximum speed for each gateway to 20 SMS per second, the "MaxMessagesPerMinute" must be set to 1200.

And your last question, the UserID and UserInfo are the only two transparent fields in Diafaan SMS Server that are guaranteed to be written back in the log table unchanged. If you need to store more fields you have to encode it in one of the two fields. We mostly use an XML record to store multiple fields in the UserInfo field. This field does not have any size limits in Diafaan SMS Server, you can store as much information as you like.
