wm2000 SPI issue

After actual testing, the clk of the spi of wm2000 is only about 150khz, resulting in a very slow spi rate. It is almost only 1/30 of the rate of the same level of mcu.
Because our application is to obtain RF information (continuous and uninterrupted biological information) through the spi interface and send it to the PC through the wifi interface at the same time.
But because the spi rate is too slow, we can't get all the necessary information in real time.
I wonder if there is any way to effectively improve the spi efficiency of wm2000?
Of course, efficiency also needs to be improved on the wifi side.
