\caption{Comparison of the performance of timer functions. All tests were performed with a rate of \SI{100}{\kilo\hertz}, with 10 64-bit floating-point numbers per sample, \gls{rc} as service type, and with the InfiniBand node-type as node-type under test. Every test contains \SI{250000}{} samples.}
