Indeed, I do not want to measure the tps if I throttle it.
The point is to generate a continuous but not necessarily maximal load,
and to test other things under such load such as possiby cascading
replication, failover, various dump strategies, whatever.

If I test a replication setup on my laptop at maximum load, I can see the
battery draining in a few seconds by looking at the effect on the time
left widget. This remark is mostly for functional tests, not for
performance test.
If I want to test the maximum load of a setup, obviously I will not do
that on my laptop, and I will not use --throttle...
