Long gaps between SPI transmissions

Hi,

in my program I would like to read an external time counter by SPI and I would like to receive a fairly accurate time. But when I starts transmissions one after another,  the difference between successive readings is ~70 us. A few us for SPI transmissions and remaining time is the gap between transmissions. How can I minimize this gap? 

I'm using SPI by ioctl.

Thanks for help.
