I got roughly the same performance results when I use the openssl speed test with and without a hifn 7956 cryto card Here's what I did: After the card is plugged in, kldload hifn; kldload cryptodev; I got the message: hifn0 mem 0xfc8f0000-0xfc8f7ffff, 0xfc8f0000-0xfc8f7ffff, 0xfc8f0000-0xfc8f7ffff irg 28 at device 3.0 on pci1 hifn0: Hifn 7956, rev 0, 32KB dram, pll=0x800<pci clk, 4x mult> Then I ran: Openssl speed des-cbc And got the following result: 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 43251.97k 44919.41k 45342.43k 45506.13k 45579.98k Then I did kldunload hifn; kldunload cryptodev and ran the same test again, and got 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 43108.10k 44917.96k 45460.88k 45532.15k 45566.26k Version of FreeBSD is 5.3-RELEASE. I believe both crypto and cryptodev drivers are supported since v5.0. My understanding is that openssl will detect the presence of an accelerator card and use it (via \dev\crypto) instead of the crypto library. Did I miss something here? TIA, Winston
