The attached very simple patch moves the commit_delay +

This appears to be a much more effective site for a delay.
Benchmark results, with and without a delay of 3000ms (commit_siblings
is 0 in both cases) are available from:

Can you elaborate how to read those results? What do "insert delay test"
and "patch, commit_delay=0" mean? Which graph should I be looking at?
