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
