Hi,
the S/W-simulated SPI is implemented by RB-100's GPIO functions and therefore its max speed is limited by the speed of the GPIO. We can boost the speed at most to 350K~400K bps by reducing the I/O-access overhead, but this may still not meet your need.
If you have a RB-110, you can use RB-110's Serial Port 6 to get a full-duplex SPI up to 12Mbps.
