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? |
