Dear All
Is it possible to download from any of the official repositories a kernel already setup to run at 1000 Hz or is recompiling the kernel from sources the only way to obatin this type of performance?
Thanks a lot
Eyes open, there is kernel-rt. And 1000 Hz is actually a performance hit.
if i install it will it break any dependencies with any preinstalled packages (e.g. nvidia drivers) or should i make a link between my old modules and the rt modules?

Why do you think a 1000 Hz clock rate gives you higher performance? What it does
is provide a quicker response than 250 Hz, at the expense of higher overhead. To
me, that means lower, not higher, performance. In the old days, 1000 Hz was used
for interactive systems, and 250 Hz for servers.
What the standard kernels use is the NOHZ option. Rather than doing scheduling
with a fixed clock interval, these kernels reschedules when a event that
requires rescheduling occurs. That provides even better response with less
overhead. I think that implies better performance.
If you still want to change, you will need to build you own kernel.
