I did not ask for the performance improvement in artificial benchmarks,
they will obviously show some :)

What I am interested in is a test showing that _in_real_world_, the system
spends considerable amount of time by passing messages. That is, a reason
for optimizing the thing at all.

Have a nice fortnight
