Hackbench (http://www.osdl.org/stp/test_details/hackbench-interp.html)
is a chat benchmark from Rusty Russel that's intended to test the
scalability of the scheduler.
The 'Metric' is the average time in seconds to do something with 100
processes. Smaller numbers are better as well as a (-) change. 'Change' refers to a percentage change in the metric from the last
completed test with results.
I've shortened the list to the 2.6.0-test kernels this time. The
2.6.0-test5-mm kernels look pretty consistent, and appear to offer a 1
second (~ 10%) improvement over the 2.6.0-test5 kernel for the 4- and
8-way systems.
