While the term can be confusing Hz, when referred to the Kernel, really just increases the interactivity of the server. Basically, the amount of timeslices the kernel produces per second (it is interrupted to do something else). At a HZ=100 setting the Kernel is interrupted every 10ms (most "older" 2.4 Kernels/custom compiled), at 512 it's approx 5ms (RedHat 8 & 9 I think) and at 1000 its every 1ms (most distro default 2.6 Kernels).
The reason many 2.6 Kernel distros compile with Hz=1000 setting is to increase the responsiveness and interactivity of the X desktop environment. A 1000 Hz setting for servers is complete overkill and will lead to excessive CPU overhead/usage. Keep in mind this option is set at compile time in the Linux kernel and can be dynamically set at boot time for FreeBSD users (which they use instead of the pingboost setting) I hope my response is accurate and informative, if not feel free to correct me.
