    Question What's your openssl speed?

    Trying to get a handle on openssl dsa/rsa speed.

    Here are my statistitics:
    CPU: model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz

    $ openssl version
    OpenSSL 1.0.0-beta2 21 Apr 2009

    $ openssl speed
    ...A bunch of results -- at the very end are the RSA/DSA stats
    Code:
          
                      sign    verify    sign/s verify/s
    rsa  512 bits 0.000327s 0.000031s   3057.4  31844.9
    rsa 1024 bits 0.001656s 0.000087s    603.7  11514.5
    rsa 2048 bits 0.010217s 0.000297s     97.9   3372.3
    rsa 4096 bits 0.073864s 0.001155s     13.5    865.9
                      sign    verify    sign/s verify/s
    dsa  512 bits 0.000278s 0.000314s   3600.2   3181.5
    dsa 1024 bits 0.000794s 0.000938s   1259.2   1065.7
    dsa 2048 bits 0.002785s 0.003296s    359.1    303.4
    Its obvious that DSA can make signatures quicker, but RSA has the advantage in terms of signature verification.

    Interested in what others may have in terms of stats!

    It should be faster than that, but the test is single-threaded (one virtual CPU at 100%, three at 0%).
