Hi
I'm running OpenBSD 4.9 on an Atom based system. On that system one disk is
encrypted using softraid. When I do "dd if=/dev/zero of=/dev/rsd0c bs=1m"
(sd0 is the encrypted softraid device) systat shows a speed of ~ 9200K and
90% sys cpu usage.
To speed up the encryption I'm looking at the vpn1411 card from soekris.
The hifn(4) man page tells me that this card is supported and the chip
(hifn 7955) accelerates AES-CBC.
Will this card help making softraid crypto faster on that system?
Regards,
Remi
