I always felt that it wasn't that useful to have the concurrency hit,
until the injection was completed.  It takes time to ramp up and down
from full concurrencyremote.  During this time you're not reaching
full performance for either sending or injection.  Unless you're out
of space on the queue device.

You don't want your todo to get too big, I'd pause injection when the todo
gets to be a few hundred messages, especially if you aren't using the
big-todo patches.
