My post took awhile until it showed up, so had already filed a bug report |
11 |
about this list not really existing. Now I closed it :) |

Sounds good. I'll start then with what I was about to post on gentoo-user, |
19 |
when I remembered that there should be this list. |

Hi there! |
22 |
|
23 |
I am a little disappointed by the performance of my system. mplayer |
24 |
sometimes stutters a little during the calculation phase of emerge -DpN |
25 |
@world, swfdec-player does so even more. Well, sometimes even without |
26 |
emerges, I guess this flash player is not coded so well. |
27 |
|
28 |
My system is not the fastest, silence and low power consumption was more |
29 |
important for me. Still, it should be fast enough I think. I have an AMD |
30 |
Athlon(tm) Dual Core Processor 4850e CPU (using -march), 4GB of memory, an |
31 |
1.5 TB drive. The whole system is encrypted (aes-xts-plain) and LVMed. |
32 |
While the LVM overhead should be small, encryption of course creates some |
33 |
extra load. /var/tmp/portage is an unencrypted tmpfs volume though. kernel |
34 |
is 2.6.31-tuxonice. I'm running KDE4 with desktop effects enabled (running |
35 |
ati-drivers), X itself takes about 30-40% of CPU time according to top. |
36 |
mplayer itself needs less than 20%. |
37 |
|
38 |
PORTAGE_NICENESS is 15, PORTAGE_IONICE_COMMAND uses ionice -c 3. I thought |
39 |
that with these settings emerges should not be noticeable. mplayer shows |
40 |
little stutters even with a niceness of 19. This looks wrong to me. |
41 |
|
42 |
The kernel is configured as low-latency desktop. BTW, the kernel config is |
43 |
here, just in case someone wants to have a look: |
44 |
http://wonkology.org/~wonko/stuff/gentoo/config-genkernel-x86-2.6.31- |
45 |
tuxonice_k8 |
46 |
|
47 |
So what I am asking is: |
48 |
1) What might be wrong? |
49 |
2) Tuning tricks. Tweaking the schedulers, different kernel sources. mm- |
50 |
sources perhaps? But they look rather old. zen-sources? I might give them |
51 |
a try. But then, I like software suspend, and tuxonice is regarded to be |
52 |
better than the normal software suspend, and even with tuxonice I tend to |
53 |
have problems. |
54 |
|
55 |
Any input is appreciated. It's not a big problem, though, I could live |
56 |
with that. But this is Gentoo, we like to tweak things, don't we? Let's |
57 |
get this list alive again. |
