Can no_hz accelerate realtime application?

In current kernels, no hz is support. But it can really accelerate realtime application?

I note that there is no clear question in your post. You do use a question mark, on a sentence phrased and structured as a statement. This does not make your meaning clear.

All of my application work for real-time application has been done in assembler, and there is no way to accelerate that code running on native iron as it already runs that native hardware speeds. To go faster, you need faster hardware.

Real-time response in the linux kernel is a slightly different thing, and does not result in maximum speed from the kernel or applications. What it does is make return from interrupts more secure, reliable, and in predictable times.

There are several configuration items that contain HZ as part of the name in the linux kernel, for adjusting times or speeds for certain factors. You may need to specify which is the one of interest to you for your specific case.
