      Ive seen a lot of talk about other crypto cards, which seem to have really low throughput (a number appear to be bested by a sandy-bridge Xeon on one core) and are PCI; Ive also seen talk of the Exar DX 1700 series (http://www.exar.com/Common/Content/ProductDetails.aspx?ID=10200&ParentID=251), which is PCIe and has very good (multi-gbit) throughput, but actually finding one is a challenge.

      Im currently trying to get one of their distributors to get me a quote, but was wondering if anyone else had any luck finding one for purchase?

        Nope, let me know if you find one, what the price is, and whether or not it works in pfSense.

        I can break anything.

          A different, but related, issue is the support of AES-NI acceleration, which is included in recent FreeBSD releases http://svnweb.freebsd.org/base/head/sys/crypto/aesni/ and promises ~4x speed for AES128/256

            Yes, I saw that, but there arent any 1w intel processors that support AES-NI ;)  Plus, in theory, the Hifn-based cards are supported now, not in 1 year (as is the case with AES-NI).

              Not sure if it's really worth spending extra money on a dedicated crypto card unless you are pumping out several 100Mb+ VPN connections.  Eventually most newer CPUs will have this built-in.

              Xeons should handle large VPN bandwidth easily.  Also software crypto are easier to update with newer ones if it ever gets broken or hacked.
