For fairly raw throughput, you can look at the test case 066-many.swift, 
in the Swift SVN at trunk/tests/language-behaviour/066-many.swift

If you change your default sites file to use your cluster, you can type:

./run 066-many

in that directory.

This test is unlikely to be able to saturate your cluster as the actual 
executions are very short - the jobs create a 0-byte file each and exit.

Also have a look at 0651-several-delay in that same directory. This runs 
1m30s delay jobs. By default 10 jobs are run, but it should be apparent 
from the source how to make it run much larger numbers.
