Re: [cwelug] Has anyone tried the 200 line kernel patch alternative in Ubuntu?

The number are there.  Re-read the post (or read it for the first time.)

The post includes a lkml link where the numbers are given:

http://lkml.org/lkml/2010/11/16/392

It all appears to be about wakeups and latency.

Linus likes it.  Fewt also likes it.  It is so hot that it is already being incorporated into distros
and remixes (such as Sabyon and Fuduntu.)

If it appears to begin to cause problems after it is applied.  It looks quite simple to me to remove it again.

I guess the question is, how much effort is it to run the objective test
to
show how much it helps.
        
If it isn't worth the time to create and run the test, then it isn't
worth the time to write the code.  In the simplest case all you need
is a stop watch and some event to time.

      
Down side is, one would need to also run the test on the 200-line patch
in
the same installation, and collect figures to show how they compare.
        
You wouldn't need to, but it would be nice.  For completeness you'll
have three comparisons: baseline to bash code, baseline to 200-lines
of C, and bash code to 200-lines of C.
