The number of TCP connections that it'll accept is likely to be much,
much, much, much higher than the number of active connections it can
deal with. Unless the application is written particularly poorly,
you'll hit kernel limitations (but maybe just a soft one, like the
per-process descriptor limit) before the application will notice.
Ideally you really need a benchmark that actually attempts to do
something with the server, like all of the http benchmarks do. Though,
i can't say I know of anything for other protocols.
