# NumParallel

The maximum number of threads to use for running the object classification task.

If you are processing video with `IngestRate=1`, using more threads means that Media Server can process a greater number of frames. This can increase classification accuracy because Media Server can run classification on multiple images.

If you are processing video with `IngestRate=0`, using more threads means that Media Server can complete processing the video in less time.

Note: The number of ``process`` actions that you can run simultaneously is determined by the parameter MaximumThreads (or Threads if you run the actions synchronously). `NumParallel` specifies the maximum number of threads to use for an object classification task that runs as part of a `process` action. Be aware that if you increase the value of `NumParallel`, Media Server can use many threads.

Note: When you use a Convolutional Neural Network (CNN) classifier, Media Server can use a maximum of one thread to complete the object classification task. With CNN classifiers, multiple classification tasks run in parallel only if they use different classifiers.
