Sorry for late reply. I need to test it after business time.   I set it to 2046->1024->512-> 256 and found NetWork IO take a low value with the number reducing. I'm sure the parameter is working for it.   For someone who will refer this ticket. The speed of data transformation will take a very low speed for NetworkIO if you set a low value to this parameter. so please adjust schedul of jobs. ... View more
