I'm generating traffic on to a physical 100G interface using an STC session in iTest. In the addStreamBlock properties menu, I have specified the interface to run at half load (which should be 50G per port), but it is consistently only running at around 10% load. I have attempted to change the load parameter, but it will always run at 10% no matter what configuration.
I've also tried to reproduce this results in Spirent Test Center 4.75 itself, but I do not run into this issue there, it only happens in an STC session in iTest.
This issue is present in iTest 7.1 and 7.2.
