As you can see, going from 2.5.34 to 2.5.36 has had a minor improvement in
response under memory loading, but a drop in response under IO load. The log
shows more was written by the IO load during benchmarking in 2.5.36 The values
are different from the original 2.5.34 results I posted as there was a problem
with the potential for loads overlapping, and doing the memory load before
others made for heavy swapping afterwards.

contest has been upgraded to v0.34 with numerous small changes and a few fixes.
