1khz for Linux is superior to the default (often 250 hz). You can
certainly feel it in online in a game server with a machine that is set
to 1Khz for the kernel. There is no doubt about that. Even TTimo (id
Software Linux developer) advocates 1Khz kernel for game servers.

Forget all crap about kernel time resolution having anything to do with
application performance. Anything above 100Hz may (because of linux scheduler
inefficiency) have good influence on desktop computer and not on server app.
Higher timer means more frequent process rescheduling and more involuntary
context switches and that means lower performance.
All you can do is wait for better process scheduler inside linux kernel.
