[solved] Resource allocation works really bad

[MaGIc laNTern]

Everything works. Works fine, so Gentoo is like my favourite Linux distribution. But it works really slowly when I am trying to run few processes together. For example, if I run compiling or file copying, I cannot listen to music (it plays brokenly) and my mouse cursor also goes very slowly. Also, if I close all the applications and run some game, it works fast and absolutely normal. FPS is even grander than I have in Mandriva Free 2007.

My kernel is 2.6.21-gentoo-r1. I tried with this and this .config files.

Here, my computer configuration.
Motherboard: Asus P5RD2-VM
Central processing unit: Intel Celeron D, 2.53 GHz
— In the kernel I have chosen Processor family: Pentium-4/Celeron(P4-based)/Pentium-4 M/older Xeon
Primary storage: 2 GB of memory by two 1GB Kingston modules with 667 MHz frequency
Video card: nVidia GeForce 7600 GT with 256 MB of DDR3 storage
— The drivers are nvidia-drivers

And, here, my /etc/make.conf.

Not sure but prescott is for dual core + have to check.

http://gentoo-wiki.com/Safe_Cflags#Pentium_4_.28Prescott.29_.2F_Celeron_D

Looks correct (the prescott) .

Might also want to add -msse3 and -m32 after -pipe. might be sse2 only have to check.

CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer -msse3 -m32"

Any idea what your -j?? is my core duo t2600 laptop 2.16ghz is at -j3 -s and it goes to max 90% load on both core's while I compile and becomes slugish same as with yours.

MAKEOPTS="-j2 -s"
-j? = cpu+1 although -j16 -s worked on my laptop and has much less problem / freezing like what you are experiencing.

-j3 / -j5 both made mine slugish and lagging.
-j16 did not weard ?

Also try same as for pentuim 4M norwood mobile cpu might make it better and have "-j2 -s" and parallel fetch.

Hope this helps.

Well, I am really scared to try various make.conf variables because I have already recompiled all the system few times. By the manual, my make.conf looks fine, after all. Maybe I can see something in Mandriva Linux where everything works okay?

Now, the trouble is solved. First, I have deleted Mandriva 2007 from my SATA disk and moved Gentoo to this disk (previously Gentoo was on an IDE disk). Then, I also enbabled DMA in the kernel. So, Gentoo became fast, very fast, really faster, than Mandriva. Thanks everyone!
