Anyway, did the ck kernel help in some way with your problem?
I will give this my full attention tomorrow, taking time to re-read
all posts and google. It might be a couple of days before I try CK's
sources, to be honest. Compilation takes a couple of hours on this
system, and I just know that I'm going to have to give it a little
attention.
After reading this thread I decided to give CK sources a go. Make
oldconfig offered me one option, whose help message made it pretty clear I
should set it. Otherwise the config was the same as I'd been using on
Gentoo sources.
Compilation took 9 minutes. After rebooting into KDE 4.5.3 I set some
more emerges going: open office, pywebkitgtk, chromium. Switching to
another desktop took 8 seconds to finish painting the screen. Not
propitious.
Once the other jobs had finished and only open office was compiling,
response was much faster, even when it got to a threaded section and was
using all four cores.
Looks like a worthwhile experiment to continue.
Also try to set these in your make.conf:
PORTAGE_NICENESS=19
PORTAGE_IONICE_COMMAND="sh -c \"schedtool -D \${PID}; ionice -c 3 -p
\${PID}\""
This will run all emerges nice 19, "idle" i/o priority and
SCHED_IDLEPRIO CPU scheduling. The "ionice" and "schedtool" utilities
must be installed of course.
I think you will love the results ;-) Given enough RAM, emerging
packages will have almost no effect on the system's usability. In my
case, I can for example watch 1080p HD movies without problems while
building OpenOffice.
