Cognex camera - Cognex OPC to Cognex Camera - Siemens S7 300 PLC - OPC server

Replace data transmission from Cognex camera <--> Cognex OPC to Cognex Camera<-->Siemens S7 300 PLC< --> OPC server. I want to specify the type of communication used is Ethernet and now I have two OPC instaled on the PC, one from Cognex , last version, that ensure communication between Cognex camera and VB HMI and another OPC which ensure communication between PLC S7300 and VB HMI. Does anyone know if replacing the flow and have only one OPC, communication Cognex camera <-> PLC< -> OPC server will be faster than Cognex camera< -> Cognex OPC? Can I save for example 200 or 300 ms? I expect opinions from those who have experience with such configurations. Thank you!
