I got access to a 1GHz VIA C3 box and tried the command using OpenVPN 1.6
and patched OpenSSL library; here are the results:

        Stock           Patched
        OpenVPN         OpenVPN

real    1m13.084s       0m47.655s
user    1m12.570s       0m47.560s
sys     0m0.020s        0m0.010s

I see a 34% improvement with hardware acceleration enabled.
