Modnet Driver Preformance

Hi Miguel,
Check out some of these tech notes:

Basically, the MaxPending is just how many requests the Modnet driver will buffer internally ready for transmission, while MaxOutstanding is how many concurrent messages can be sent. These settings really need to be tuned depending on the hardware you are communicating with. I have seen some devices that only accept 1 request at once (MaxOutstanding=1) while others can accept up to 32 parallel messages without issue. The more messages you can send in parallel, the better your throughput. Always respect the requirement that MaxPending is greater than MaxOutstanding.
