Hi, everyone,

In first place, let me publicly thanks both of you (Info and Con) for
your great work at fixing/tuning the 2.6 scheduler to its best.

Now that Ingo seems to be working again on the scheduler, I feel that
Con and Ingo work is starting to collide. I have been testing Con's
interactivity changes to the scheduler for a very long time, since it's
first O1int patch and I must say that, for my specific workloads, it
gives me the best end-user experience with interactive usage.

I just only wanted to publicly invite Con Kolivas to keep on working
with the scheduler patches he has been doing and that have required a
constant and fair amount of time from him. I don't know if Con patches
do work as good for others in this list as for me, so I also invite
everyone who is/has been testing them to express their feelings so we
all can know what's the current status of the 2.6 scheduler.

As the last point, I do want to invite Ingo and Con to work together to
fix things up definitively. I feel Con scheduler patches give better
interactive results (at least for me) but still feels a little bit slow
when the system is under heavy load and I try to launch new processes,
like a new xterm, for example. On the other side, Ingo patch makes the
system feel much more responsive under heavy loads when launching new
processes, like opening a new konsole tab, but still suffers from
jerkyness on interactive tasks, like the X server.

I think the more people working on the scheduler, the more probability
we have of fixing/tuning the last pieces of code so we can enjoy a full
enterprise-level, but well-behaved with interactive jobs, 2.6 scheduler.

Thanks for listening.

Second the thanks.

I don't see much subjective difference between test1-mm(x) and
test1-G2.  I've never gotten an audio skip anyway. The only
skipping I can get is video only skips under xine, but the audio
doesn't skip.

I guess this may be in part due to how I load the machine.  Any
meaningful comparison of the two bodies of work would have to
be made with (at a minimum) a standard set of loads.

The way I loaded my machine (dual Xeon HT) to > 9 load average
was: 1. continuous loop 'ps -ef', 2. KDE make -j8, 3. pov-ray
rendering, 3. continuous bitmap operations in X.

What I've left to date is (among others): 1. heavy disk i/o load,
2. heavy network load, 3. deliberate memory torture.

Operations such as new terminal window, new browser, new Konquerer
etc, are slower of course, and somewhat jerky, but given a load
of 9, even Mozilla and Konquerer loaded in < 15 seconds, a new
terminal loaded and accepted keyboard input in less than 3.

So I wonder if the seemingly disparate results are weirdness,
or are they a combination of basic machine variations coupled
with loading variations?
