One interesting part of tiotest is the latency measurements.
Latency isn't printed by tiobench.pl though. I think it's
valueable information (and wish I had it).

Agreed. I'm glad kernel hackers focus on latency too. :)
There are _some_ applications where throughput is critical
though. I would prefer to measure both throughput and
latency at the same time, but am not yet clear on how to
deal with the Heisenberg principle.
