A meaningful container size does not hamper performance. I am in the process
of getting more results (with varying container sizes). Please let me know
what you think of the results? Would you like to see different benchmarks/
tests/configuration results?

Any feedback, suggestions to move this work forward towards identifying
and correcting bottlenecks or to help improve it is highly appreciated.

Memory reclaim tends not to consume much CPU. Because in steady state it
tends to be the case that the memory reclaim rate (and hopefully the
scanning rate) is equal to the disk IO rate.

Often the most successful way to identify performance problems in there is
by careful code inspection followed by development of exploits.

Is this RSS controller built on Paul's stuff, or is it standalone?
it is based on Paul's patches.

Where do we stand on all of this now anyway? I was thinking of getting Paul's
changes into -mm soon, see what sort of calamities that brings about.
I think we can merge Paul's patches with *interfaces* and then switch to
developing/reviewing/commiting resource subsytems.
RSS control had good feedback so far from a number of people
and is a first candidate imho.

Thanks,
Kirill
