Performance

Production

The speed ultimately is determined by

how fast you can prepare the messages
network bandwidth
performance on the remote side (SMPP Server)
how fast you can process responses

On good tuned production systems you can reach 500 messages/seconds.

Tuning

You can try to play with following optimization parameters:

Change number of threads that process received messages. Dafault is 3.

client.WorkerThreads = 10;

Change receive or send buffer size for the TCP socket

client.ReceiveBufferSize = 32 * 1024 * 1024;
client.SendBufferSize = 32 * 1024 * 1024;

A larger buffer size might delay the recognition of connection difficulties. Consider increasing the buffer size if you are using a high bandwidth, high latency connection (such as a satellite broadband provider.)
