BX3105 throughput (TCP/UDP)

i could not find a way to determine what is the best streaming throughput i can achieve while using BX3105 with a UART host interface, would it be 3Mbit/s ?.
What would it be if i was using an SPI interface ?
What if i would need to transfer 10MBit/s on the WIFI channel ?

For maximum baud rate of UART, it is mentioned in PTS.

For SPI clock speed, I tried to communicate in 13MHz, it is not working.
But it is working at 6.5MHz.
Maybe you can give a try on 10MHz.
