It is a rather recent feature developed by Gary and it will be great if Gary
will comment.

Still, you are keeping 20 clients, which are testing 20 paths.
Could it be that 6000 clients will do the job? Give it a try.

Just keep in mind, that by default you need for 35K of memory per each
client
and ramp-up about 100 not to start all them at start-up.
