In perl, you could do this by scripting a quick benchmark
with LWP & Crypt::SSLeay libraries. ( LWP loads Crypt::SSLeay
on the backend for https URLs )
Here's a crude command that will set 2 web clients hitting
your SSL server at the same time:
]$ perl -MLWP::Simple -MBenchmark -e 'fork; timethis(25, sub {
]get(qq(https://localhost/)); }); wait;'
timethis 25: 11 wallclock secs ( 2.78 usr + 0.07 sys = 2.85 CPU) @ 8.77/s (n=25)
timethis 25: 11 wallclock secs ( 3.03 usr + 0.07 sys = 3.10 CPU) @ 8.06/s (n=25)
The timethis() stats aren't really relevant in this case, but
it gave 50 requests done in 11 seconds. Obviously, since the
client was running on the same machine as the server, the servers
real performance would be quite different by itself.
