Yeah, I could buy a nicer fan. I don't want to bother with it though. |
| 13 |
The fan is clean and well lubricated. The heatsink is low-profile and |
| 14 |
it requires a lot of airflow -- the fan has to spin fast and it's not |
| 15 |
going to be silent when it's running, the case is too small and it's |
| 16 |
a hot-running processor. |

NFS. The whole point of swap for me is for efficient use of existing |
| 21 |
memory. a few megs of swap go a long way keeping the system responsive |
| 22 |
when the ram gets well loaded. |

I can do so on the nfs server. The fact that it's on NFS interferes, I |
| 26 |
guess. The diskless says: |
| 27 |
| swapon: swapfile has holes |

I recently was given a laptop with a work battery, and it doesn't |
| 36 |
unmount anything when I suspend it to swap. Hans-Werner Hilse explains |
| 37 |
in his response how one might resume from a remote disk. |

I have, but unless cpufreqd disagrees with cpufreq-info as far as |
| 42 |
hardware limits: |
| 43 |
| slim / # cpufreq-info | grep limits |
| 44 |
| hardware limits: 2.10 GHz - 2.40 GHz |
| 45 |
i don't think it's going to do any good. between 2.1 and 2.4 ghz, |
| 46 |
there's virtually no noticable difference (in performance _or_ temp). |
| 47 |
I just want to suspend it when it isn't doing anything so it doesn't |
| 48 |
make any sound but only takes a few seconds to start up. |
| 49 |
|
| 50 |
So that's kind of what I was thinking. |
