O.K. I let the automated test finish the 3 processes stuff
(which is 1/2 way).
The newly compiled code is now running, but I only resumed
the test, I did not re-start it.
A comparative graph of the 1 & 2 process results is attached.
(the previous version of this same graph was on another thread).
Legend:
Control: older kernel compiled with CONFIG_NO_HZ=no
c308: Kernel with the earlier commit
5aaa: Basically, Kernel 3.5 RC2
Wang: Charles Wang's first proposed solution.
Peter35: Peter Zijlstra's current proposed solution.
Summary: Extremely good.
