You run one or more swift-bench-client processes like this:
$ swift-bench-client 127.0.0.1 20001
$ swift-bench-client 127.0.0.1 20002
Then you run swift-bench with a new option, --bench-clients (-b), which is
specified once for each swift-bench-client:
$ swift-bench -b 127.0.0.1:20001 -b 127.0.0.1:20002
You get log lines from each client (interleaved) along with a final report
for all clients:

swift-bench 2012-08-25 22:45:27,550 INFO 2000 DEL **FINAL** [20 failures], 237.1/s
The concurrency, PUT count, and GET count config settings are divided by
the number of bench_clients. In other words, the same volume of work is
attempted (vs. not specifying --bench-clients), but it can now span
servers and CPU cores.
Benchmark containers are created (if use_proxy = yes) and deleted (if
delete = yes), with appropriate concurrency, in the initiating
swift-bench process, not any of the swift-bench-client processes.
