I'm using a HP Proliant Server N40L.
When uploading a file via ftp to an encryptet disk (AES-CBC) i'm getting 70MB/s (610MBit/s).
Is it possible to increase the speed by using a Cryptographic Accelerator like this:

Re: Cryptographic Accelerators
Hi Tron44,
It might make a small difference, but your speed is within the nominal range for the task. I would be surprised if you achieved more than a 10% change. Maybe someone else who has actually tried this type of card will volunteer another opinion.

Re: Cryptographic Accelerators
Note that "Wire Speed" of a gigabit nic with overhead works out to about 700-750Mbs, so you will not get much boost here. Look at your performance graphs. When you are doing the copy, is the CPU maxed? Or is your source maxed?

Re: Cryptographic Accelerators
70 mb/sec is really good.
my i5 with aes-ni only reaches around 90mb/sec via samba.
from the specs of the chip:
500-Mbps system throughput
• DES-CBC, 3DES-CBC
• AES-CBC, AES-CTR (up to 256-bit key lengths)

so the specs say no.
