Hello,
I've been testing with an "Broadcom CryptoNetX SSL800" card and the
performance (when testing with openssl) is a bit disapointing. I would
expect about 800 (or nearly 800) sign/s, but in stead the card+openssl
only do about 94 sign/s (with 1024 bit RSA keys). This is less than one
eigth of what I expected. Am I doing something wrong or is there some
magic that I need to perform?
Rene
