Hi Fergus,

Yes, that would be too much. The optimum depends on how many gateways you use and whether you tend to send single messages or bulk messages in batches. Using a MaximumBatchSize of more than 10 is most likely not useful for the Clickatell Gateway. The same is true for GSM Modem Gateways. When you use more than 50 3G modems and send messages in large quantities, a MaximumBatchSize of 20 is probably optimal. But for less than 50 3G modems a value of 10 or lower is usually better.

For the SQL Connector the MaximumBatchSize is set to 500 because database operations are much more efficient in large chunks than in single (1 message) operations. There is almost no disadvantage to use a larger setting.

Hi Rick,

The MaximumBatchSize setting determines how much messages a Gateway or Connector can process concurrently. The relevance of this setting depends on the type of Gateway or Connector.

For the GSM Modem Gateway a MaximumBatchSize of 1 is sufficient because the gateway can only send 1 message every 3-6 seconds and the overhead of getting a new message from the central message queue does not slow it down much. For systems with multiple GSM Modem Gateways it might even slow down message sending because messages are sent with one GSM Modem instead of using round-robin to distribute the messages evenly over the modems.

For the SQL Connector a MaximumBatchSize of 500 is a good setting. It means that messages are read from or written to the database in chunks of 500 messages max. If the MaximumBatchSize is too low or too high it can slow down message processing or have too much impact on the database resources.
