hardware crypto questions

[D. Goss]

I have an option to get a PCI crypto card based on the Broadcom  
BCM5820 chipset.  I see the card is still listed as current at  
Broadcom's site and that it is supported via the ubsec(4) driver in  
FreeBSD.

Does anyone know a few of the various common and current crypto  
cards?  I am having a hard time finding any benchmarks or comparisons  
of various cards and can't tell what to expect from this hardware.

Also, can someone point me to a utility or method of benchmarking  
before/after this card (software vs. hardware) specifically for SSL  
transactions? (Card is intended to go into server doing some HTTPS  
commerce transactions.)  Server is almost-current dual 2.8Ghz dual  
core x386 machine.

Thanks you -
