The table below details the expected peak achievable UDP/TCP throughput numbers for a Quad Serial Peripheral Interface (QSPI)/Serial Peripheral Interface (SPI) master clock rate of 24 MHz, and where the networking stack executing on the host is not a limiting factor. These numbers are projected using measured raw QSPI/SPI master packet transmission rates.
