Unexpected results when measuring MPU6050 sample rate with RaspberryPi
First of all, my time measuring was faulty. I've noticed that during data sampling intervals systemcalls do not increase my measured overall time, wallclock time was much higher. After raising i2c port speed from 100khz to 400hz i was able to get 4 times as much samples. So i assume,that I've encountered i2c bottleneck
