If you have CONFIG_HZ=1000 then it should be ok assuming this is about a
desktop/notebook. Afaik CONFIG_NO_HZ is a power-consumption related
setting, setting this option makes the kernel timer only wake up when
requested while setting it at 1000Hz activates it all the time. Not sure
if I worded that right, I'm not a kernel expert. With respect to
performance implications I can't say anything sensible. I'm using
kernels with CONFIG_HZ=1000 and CONFIG_NO_HZ=y side by side and haven't
noticed any real differences so far.

Afaik that's not necessary.
