Before I started using MATLAB Parallel Computing Toolbox, I often set the priority of MATLAB in the Task Manager in Windows as either High or Realtime to speed up the execution. Now, after running a code using the aforementioned toolbox, I started to see several instances of MATLAB in the list of ongoing processes, so which instance should I increase its priority to gain more speed? Should I change them all? Does changing the priority even has any effect in terms of speed in this case?

Thanks for your time to answer this question, but I think the answer to this question is still open.

The MATLAB central file linked in Edric's answer should let you modulate priorities when called within an spmd block:
Regarding on whether it would help or not, I would think that it depends on the number of resource-hungry processes that you have running on your machine. Basically, if you close all the other programs you have running besides MATLAB then setting a higher priority should not significantly affect the performance of your MATLAB workers.
