Absolutely no need to reinstall.

volk_profile will provide gnuradio instructions which algorithms perform the best on your system. gnuradio already has them all (or in fact: it links to libvolk which has them). When this is done your performance may dramatically improve from the generic algorithm to one that is specifically optimised for your system.

Why isn't this done automatically? Specific cpu instructions might not be available to your system (such as: SSE works on Intel but not on ARM. While Neon works on ARM but not on Intel).
