|
| another question is, is there logic, either in the driver or in openssl,
| to notice if crypto operations are getting backed up waiting for the
| crypto card while the main cpu is idle and, in that case, to start doing
| the crypto on the main cpu rather than on the crypto card?
|
| in other words, if the main cpu is actually way faster than the crypto
| card, is it possible that the crypto card could actually _slow_ crypto
| operations on that system?
|
| last time I checked, the stats on the cheap soekris cards were way slower
| than the output of "openssl speed" run on my system during normal load....

how would one test this out: just run % openssl speed on a system with the
card, and then again without the card?

where are you referencing your stats from?
