> The current default value of planner.partitioner_sender_threads_factor is 1.
> This is too low for most requirements. In one scenario the elapsed time of a
> query on a 20 node cluster went from 158 secs to 60 secs when increasing the
> value to 2. However, we have to determine a reasonable default for this and
> related partition_sender settings.
