 Posted: Sun Mar 27, 2005 4:31 am Post subject: Optimal kernel configuration |
 |
|
Hi everybody,
I've been running the vanilla sources for some time and have had them stripped down nicely so that they only have the stuff I need on them or might need in the forseeable future. However, switching between windows can be sluggish when I'm emerging (especially when I do an emerge sync).
I was wondering about the hpet_timer option. I have a Pentium 4 with hyperthreading. Will enabling that give me better performance? Is there anything else I might wish to consider configuring that might boost performance?
I'm emerging ck-sources now, so maybe that will do the trick.
Best,
Alex |

ck-sources has been pretty good to me. And I've tried out the nitro sources, but I haven't really noticed much from them, so I think I'll be switching back to ck, but I'm too lazy to reboot 
I don't know about hyperthreading since I run a athlon-xp here.
I've also found that renicing X to -10 helps out

No, enabling HPE timers will have no noticeable effect on your system. The only situation where HPETs make a difference are realtime low latency applications, such as high end sound processing and other multimedia stuff. And that's of course only if your chipset offers the corresponding hardware support, which I don't think it does in your case.
There's not much you can do on the vanilla patchset to boost interactivity performance. Like the above posted suggested, try using ck-sources or gentoo-(dev, i.e. 2.6)-sources for a desktop system. The vanilla kernel sources are geared more towards server usage.

I just finished compiling the ck-sources and rebooting. So far the switching problem appears to be gone and performance is, I think, noticeably snappier. If I get around to it, I'll follow some of the pointers on that thread, but things appear to be going well now.
The other thing I'm considering doing in the future to improve my gentoo experience is to switch from KDE to E17. I plan to wait for KDE 3.4 and E17 to come out as that way I can emerge the bare minimum KDE stuff I want to run (konqueror, k3b, and kile) and have it working in a pretty and small wm. More fun all around I think!
Best,
Alex |

Hi,
Cool, though it's still masked. I know I can unmask it, but I'd just prefer waiting for E17 to become stable too so that I can do both at the same time.
Thanks.

Hi, I am giving try to ck-sources. After "make menuconfig" my new .config is same as .config- 2.6.11-gentoo-r4 (only 4 lines are different, but they begin with #).
So would be ck-kernel different from my existing gentoo-kernel, or should I modify some lines to see advatages of Colins patches?  |

No.
Colin's patches don't add new menu entries for the most part, they alter the memory management and process scheduling subsystem to provide enhanced desktop performance. There's no need to fiddle with the .config manually, especially not if the .config worked just fine for your previous system.
