I think SPI runs at 500 KHz. That is 50 times slower then Ethernet if you look at only the bit rate. But what matters, I think more is the time it takes to send one message. It might (maybe?) be faster on SPI because you avoid the TCP/IP stack. With SPI your software is driving the bare hardware.
Sometimes a car at 55 MPH can beat a 550 MPH airplane if the trip is short enough. I don't know about this case but it's kind of moot as 500KHz is well more than fast enough.
