7 Smaller numbers here actually mean less clock interrupts per second.
8 This means that the CPU doesn't have to spend as much time switching
9 between processes. However it also means that a process will have to
10 wait longer if another one is currently using the CPU. Higher numbers
11 tend to be good for getting faster responses, since the process on
12 average shouldn't have to wait as long to actually get back on the CPU.

14 I believe the help messages suggest 100Hz for a server, where
15 responsiveness is not a problem, you just don't want the CPU wasting
16 time switching processes lots. 250Hz and 300Hz are for more for desktop
17 machines, and the 1000Hz for a really low latency desktop machine. So
18 have you tried the high speeds?
