-====== Cyclictest - Number of measuring threads ====== 
  
-The threads option (--threads) is used to specify the number of measuring threads that will be used by Cyclictest when detecting latencies. In general, it is a good idea to only have one measuring thread running on each CPU on the system. ​ 
- 
-This option is also crucial for minimizing the effect that running Cyclictest has on the observed system. When using Cyclictest, it is important make sure that only one measuring thread is intended to execute at any given time. If the intended execution times of two or more Cyclictest threads overlap then Cyclictest'​s measurements will be influenced by the latencies caused by its own measuring threads. The best way to make sure that only one measuring thread is supposed to execute at a given time is to have only one measuring thread executing on a given CPU.  ​
