Here are the results of some tests run on OCF under linux. The platform was a 533MHz Intel Xscale IXP425 platform (ARM big endian). The board has a Safenet 1141 and a Hifn7956 on the PCI bus and also the IXP425 has a built in crypto engine. The are three sets of results, the first is crypto performance using openssl speed, the second is using scp and the final shows CPU usage while running "openssl speed".
The following tests were done using the following commands.
openssl speed -evp des -elapsed
openssl speed -evp des3 -elapsed
openssl speed -evp aes128 -elapsed
"-engine cryptodev" was added to the command when OCF acceleration was desired.
The OCF modules used are:
none - completely user mode software crypto
soft - using crypto framework with software crypto engine
ixp - using crypto framework with IXP crypto engine
safe - using crypto framework with safenet crypto engine
hifn - using crypto framework with hifn7751 crypto engine
I dropped the max packet size down to 2048 bytes, 8192 seems a little
unrealistic. Needless to say, the HW crypto is even further ahead if 8K
buffers are used.

The following tests are the same as above only 10 threads were run in
parallel by adding the "-multi 10" option to openssl speed.
