-Cyclictest measures the latencies that occur in the one particular situation for which it is configured. In other words, running Cyclictest once will not identify all the possible latencies in all possible situations on a system. If Cyclictest is being used to debug a latency, the options should be chosen with the goal of observing that latency. However, if Cyclictest is being used to globally evaluate a system'​s performance,​ then many different runs of Cyclictest with different parameters are required.+Cyclictest measures the latencies that occur in the one particular situation for which it is configured. In other words, running Cyclictest once will not identify all the possible latencies in all possible situations on a system. If Cyclictest is being used to debug a latency, the options ​and system load should be chosen with the goal of observing that latency. However, if Cyclictest is being used to globally evaluate a system'​s performance,​ then many different runs of Cyclictest with different parameters ​and loads are required.
