I am not an expert on Ethercat, but normal Ethernet timing can vary a LOT depending on the hardware. Some Ethernet cards are very good and some are not. Some of this depends on how the card is built and some on how smart was the software guy who wrote the driver for the card. I remember swapping out a built-in Ethernet for an Intel brand PCIe card and seeing a large decrease in CPU utilization.
So my point is that this may be hard to fix if different people have different hardware.
