SD card interfacing via SDIO - low throughput

Question asked by arbitrer on Jun 5, 2015
I was able to compile and run the code provided by Tilen from his web-site,

So I can mount , write and read data from file. But when I measured the throughput the measurement was very disappointing for read operation I got only 500KB/s which is lame for an SDIO operation,

I calculated the throughput but toggling a GPIO before and after read/write operation, for example

GPIO_ResetBits(GPIOD, GPIO_Pin_4);

Is there something that I need to do , in-order to get a better throughput about 5-7MB/s
