In many cases, VIs that test multiple sites or pins contain For Loop structures that perform computationally expensive or time consuming operations for multiple instruments. Often, you can improve execution speed by enabling parallel iterations on the For Loop structure. Not all For Loops can run with parallel iterations, and in some cases, a For Loop does not benefit from parallelization. Additionally, you can adjust thread settings for parallel For Loops to improve performance.

Refer to the Parallel Iterations: Improving For Loop Execution Speed topic in the LabVIEW Help to determine whether you can improve performance by enabling parallel For Loop iterations in VI test code modules. In LabVIEW, select Help » LabVIEW Help to launch the LabVIEW Help.
