Review comment:
@leonardBang I see your point and I didn't realize it's distributed
access to HMS. In that case, I'm fine to keep the threshold as it is. Perhaps
we should worry more about how many tasks can concurrently access HMS, than how
often they access.
One more suggestion about the log message: I think `"Currently the
recommended value of '%s' is at least '%s' when set...` is easier to understand.
