[issue1542] bad crypto performance (using openssl)

[Alex Hornung (via DragonFly issue tracker)]

New submission from Alex Hornung <ahornung at gmail.com>:

Results of a few tests on my soekris net5501 box (no, I'm not using the crypto 
hardware; yes I am sure about that):

Results of the same tests on the same VMWare virtual machine:
