Optimize measurements #10

Closed PhilippWendler closed 6 years ago

PhilippWendler commented 7 years ago

We want the measurements to work with as little overhead as possible. Currently for every single measurement (i.e., four times per cpu per measurement interval) the device file in /dev/ is opened. This could be optimized at least to read all values at once, or even just opening the file during initialization and then reusing the same file descriptor.

This should be done after #9.
