arduino How to control multiple SPI''s Stack Overflow

I am having a weeny trouble with my SAMD21 board. I have got this starter kit (schematics) and I want to add some more sensors. They use SPI, so I programmed them. Since SAMD21 got the code it lag''s everytime, when code reache''s the sensor begin function. Please give me some advice, how to control both SPI''s correctly and avoid lags.
