FWIW: Here are scripts I've been using for LST runs. 'sim_tests.sh' runs 
tests in serial, parallel is...

The 'sim_config' is an easy way to manage different machine configs - 
just set the CONFIG environment variable to the particular file you'd 
like to use.

The cli format is "test size loops" where:
    - test can be 'read' 'write' or 'ping'
    - size is anything <= 1m, i.e; '243k', '2342', '1m'
    - loops is the number to send.

There is a 'NCONN' environment variable that controls the --concurency 
for LST tests, bascially how many RPCs to keep on the wire.

YMMV,
Nic
