Well, for sure I have not kept up with all these issues. But some |
| 15 |
kernel versions ago, there was heavy work on the I/O and various schedulers, |
| 16 |
memory management etc etc. All of these settings effect the processor(s) |
| 17 |
speeds, idle etc. I started reading about overclocking my FX-8350 after I |
| 18 |
got the water cooler installed and realize about a year ago, |
| 19 |
many, many things have changed. So I guess what I'm saying is this |
| 20 |
subject get's very complicated very quick, with lots of new options |
| 21 |
for performance tuning on a system. |

I'd read up a bit and find similar things that folks have done to "optimize" |
| 24 |
a workstation (laptop) for speed or economy (power consumption) and start |
| 25 |
with that before tweaking and testing the myriad of things that can effect |
| 26 |
your system's overall performance. On laptops, some graphics hardware can be |
| 27 |
put to sleep for substantial power savings, along with tricks on HD |
| 28 |
operations...... |

Surely monitoring the cpu temerpatures is the best place to start, but |
| 31 |
there is so much more to tune now, kernel and otherwise. |

Arch Linux has some nice docs that may get your research going: |
