Issue Details

Does running with multiple threads have any effect on other applications?


Yes. Each thread is scheduled independently by the operating system, so applications with more threads will tend to get more CPU time. Therefore, other applications may appear to run more slowly when LabVIEW is running several VIs in different threads at the same time. 

For LabVIEW 8.0 or later, refer to the Multitasking, Multithreading, and Multiprocessing topic in the LabVIEW Help (linked below).
