We’ve found these worst-case events to occur intermittently and vary depending on: The worst-case call time can also be much longer, several milliseconds in fact, depending on the task management of the operating system. Ten “get” calls on ten unique devices will yield 100 calls per loop, which would be 30ms (although Phoenix has optimizations to reduce this explained below).
Many of you may think that does not sound like much, but consider the number of get calls you execute on your peripheral devices per loop. These calls average approximately 0.3 milliseconds. However the LabVIEW VIs appear to not be buffered and may experience this call delay. Most (but not all) of these are buffered in WPI C++/Java so they actually get called once every ~20 ms, regardless of how often you call getters.
