Yepp. Speedfreq is on "dynamic" policy.
On Performance the cat /proc/cpuinfo tells about
| Code: |
cpu MHz : 1298.905
bogomips : 2580.48
|
|
So when you compile OpenOffice, put it on the performance policy. Then, it will still take ages to compile, because it's huge and there's nothing you can do about it. However, it should take half of the ages as you'll be running almost twice faster than when saving batteries.

dynamic policy will equals performance et high cpu load. So it won't change anything.

... if it's working, of course. I assumed that the /proc/cpuinfo information was taken when the computer was with high load compiling OpenOffice.

That confuses me a bit - mine doesn't seem to work. When I echo it into scaling_governor, nothing happens - but it's in scaling_available_governors.
And it seems a bit odd - I thought the philosophy was to keep it out of the kernel if possible? But this new governor brings speed modulation back in. |

I am using the cpudyn daemon, it deals quite well with the issue.

as root i just did | Code: | | echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor |
(while in x and all other scaling programs not running)
open aterm run as root | Code: | | watch -n1 cat /sys/devices/system/cpu/cpu0/cpufreq/cur_cpuinfo |
no open firefox, open gimp, you should you processor speed change.
I was using speedreq, but I like this a lot better.
**note** I am in class right now and on the computers in teh E-Bus lab so I am not sure about the exact file location or file name, but the ones i provide are very clsoe if not exact

ondemand powersave userspace performance |
I am guessing when you say dynamic you mean putting it in userspace and using a program such has cpufreqd, cpudyn, speedfreq.
This difference is that those are programs modify a file that the kernel monitors and changes the cpu according to that file. Too me, this is wasteful, you have a program monitor your cpusage and then writes to a file, which the kernel is monitoring and then changes the cpu speed.
OnDemand is a governor, so you set it, and then you don't need any other program to dynamically change the cpu, the kernel watches the cpuusage and then changes the speed accordingly.
I have used cpufreqd and speedfreq and notice a lot less latency in using ondemand as compared to userspace with a program.
then I wrote a small script that switch b/w ondemand and powersave. I siwtch to powersave when I am just browsing the web and I don't want to speed up the processor just open a few pages at once

FWIW, I installed ubuntu linux on my asus m6ne16. I was worried about compilation time, was planning to use the laptop in battery mode most of the time, and wanted to try out ubuntu.
Most of the stuff was autodetected and worked out of the box, and the packages are quite recent. I'm keeping gentoo on my laptop, but I'll probably keep ubuntu on the laptop :-) |

Well, all the tools that you might need are readily available (kismet, airsnort,...), together with all major card drivers (orinoco, prism, aironet, ...). So you should have no problem at all.

My laptop is refurbished, but Gentoo works great  . I would never think of using anything else on it, and speed is not an issue.

The only install I have of Gentoo is on an HP laptop. Everything works, no complaints at all.
When I'm sleeping, it's compiling.... |

Here is something for all "It's too old for KDE"-people: An old Compaq Presario 1247 K6-2 (400 Mhz) running everything with CFLAGS mcpu=k6-2 and using distcc to transfer all work to a fast PC. KDE and Openoffice are running perfectly (sometimes a little bit slow when starting - but running and running and ... no Blue Screen at all).
To summarize: You got a laptop? It's new or old? You wanna use Linux - not Windows? Get Gentoo.org with custom build settings and it will be the last time you will have to install something from scratch.
Perfectly to connect to any network: Samba, NFS, OpenLDAP, ... 
Install NOW!
(This message should show, why Gentoo.org is sometimes superior to other distributions - you can build it for your CPU - not just for i386 / i686). |

Certainly. Last month I decided to try it on my Toshiba Portege 7220, never having used Gentoo before. (I liked the idea of Portage on a Portege) I followed the instructions to the letter, and everything so far has gone without any major problem. I have got networking, printer, scanner, and external CD writer all working. The only hardware I have not got working is a wireless link, but then I have not yet tried.
KDE took nearly 3 days to compile but worked immediately. I have installed some fairly unusual programs such as Gramps (genealogy) and Lilypond (sheet music printing) without any trouble. In the past these posed problems. I used to use SuSE, and while this is generally an easy-to-use and stable distro, some bugs showed up on the laptop. Also the 9.1 distro was slow in comparison; Gentoo was much faster from the outset, even though I had forgotten to set up the swap partition in /etc/fstab at first!

Gentoo running nicely on my IBM Thinkpad 570.
Just bought an 80 GB HDD so I can make it a server (I t came with a 6GB disk, which turned out to be a bit small for a full Gentoo installation, definitely when building OOo.)
The screen (or lint-cable) is somewhat broken, so it's not really laptop-able anymore

Well, i would have to got for gentoo. My laptop is considerably more slower then yours; a celron 1000 mhz with 128 mb ram. And i compiled everything from source on it, without distcc.
I have written documentation explaining how to install gentoo on it (Toshiba sattelite 6000C) but i have not submitted it to www.linux-on-laptops.org yet, since i have to read over it.
If anybody would like to read over it and maybe point out some thing i have done wrongly i would be happy. The document could be found at http://benne.heima.biz/toshiba/. You may contact me with a PM.
