Hey, i wonder which scheduler you people have the best experiences with,
staircase or nicksched?
personally i were using nicksched for a long time, but then i tried
staircase, and i like it overall more,
with nicksched its like, 1 process gets good prioity, so that if tvtime
is running, it runs perfect, but moving windows and stuff will be not so
fluid.
with staircase, the overall performance is not as fast, but
interactivity is really good, like tvtime runs fine, moving windows are
fast as lightening, setiathome can also run perfect.

I personally like staircase, i also used to use nicksched but i prefer
staircases simple design and structure. Nicksched was pretty fast but
twiddling around all day with renicing X and now the HT issues are
annoying and staircase has always worked perfectly for me without
flipping fifty switches in the cockpit.

The HT issue should be fixed (I hope).
Why did you have to "twiddle around all day with renicing X"? I realise
you're overstating, but you really should be fine with just setting X
to -10 at startup and be done with it.

Thats -mm2 but I can't find patches that fix the HT problems in that
thread, mind pointing them out?

I'm using staircase exclusively, but I did compare it to vanilla kernel's
scheduler and yes the interactivity is very good (I'm running x.org and KDE
3.2.3 here).
I have had no sound skips or tvtime problems no matter what kind of disk IO
was being done, which includes MySQL database updates, cron scripts (running
rpm -V on all packages) and wwwoffle purging cached files (note I use the
default as IO sched). Also kernel compilation is no threat to interactivity
with staircase.
I'm a Mandrake user and since the release of Mandrake 10 it does not renice X
server to higher priority so I guess Nick's scheduler would force me to tweak
X startup script.
The other things I like about staircase are that it gives you kernel.compute
and kernel.interactive sysctls that allow to perform serious computational
tasks with it. Also ability to use scheduling policies with schedtool is a
great plus, for example using SCHED_BATCH for cpu bound applications like
seti@home or folding@home.
Overall staircase has been a great experience for me.

Hmm, OK I'll have another look at it. Thanks.

I've been a fan of Staircase's for a long time; it simply responded faster
and launched progs faster.
I haven't tried nicksched in a while, but it didn't perform as well as
Staircase.
Having a batched mprime torture test in the background still allows me to
play a movie in mplayer, compile a kernel, listen to a CD and browse
the web without glitches. Not that I'd normally watch a movie and listen to
a CD at the same time ;)
Going to try Nicksched again RSN to see if it handles the same load, but
still I have to say I'm mighty pleased with Staircase and the rest of
Con's patches.
(Running 2.6.8.1-cko3 with the lenient patch of -ck6 at the moment)
(This is in an Athlon 1.3GHz with 512MB of RAM and roughly the same of swap)

Just gave -rc1-mm3 a shot and had my filesystems say bad things.
shrike kernel: reiser4 panicked cowardly: assertion failed: extent_get_start(ext) == extent_get_start(&uf_coord->extension.extent.extent)
/bin/sh: line 1: 4407 Segmentation fault rm -f fs/xfs/.xfs_bmap.o.d
Didn't get around to renicing X, but anyway, app launch time was longer
and the music did twitch a bit when starting the simultaneous kernel
and glibc compiles. So I'm still on Staircase and don't see any reason
to change away.
I retried running as much cpu-intensive stuff as I could on cko5, basically
ck6, and everything was smooth. Respects to Con for that :)
This is not a troll nor a flamebait, but an honest question.
Should the need to re-nice X not be seen as broken behavior?
Then on to the Reiser4 issue:

In my config I have:
CONFIG_REISER4_FS=y
CONFIG_REISER4_LARGE_KEY=y
CONFIG_REISER4_CHECK=y
CONFIG_REISER4_DEBUG=y
CONFIG_REISER4_DEBUG_NODE=y
CONFIG_REISER4_EVENT_LOG=y
Going to try -cko5 without debugging, just for shits and giggles :P

undoubtedly call it a bug or tuning, depending on point of view.
