Hi @Matt Clarke.. I have a related question regarding concurrency .. I have an issue that I have a dataflow with two connected processors (each with concurrent tasks=1), but when I set the number of threads of the whole instance to 1, the two processors still manage to somehow run concurrently although I expect them to run sequentially .. The first processor takes on average 2.5 seconds per input and the second processors takes on average 4.5 seconds.. I gave it 100 inputs and I was expecting it to finish in around 700 seconds (i.e., sequential execution) but it still manages to finish in 480 seconds which suggests that each processor is using a separate thread and they do not wait on each other. Am I missing something here ? ... View more
