Hi Evgeniy,
Just interested in the results you are getting below for
comparison to what I see under OCF with Openswan.
What sort of hifn card were you using in the test below,
was it a 7956 PCIX (ie., 64bit?)
How did you measure the throughput ?
I can post the OCF numbers, but it doesn't mean a lot
unless it's a fair comparison :-)
Cheers,
Davidm
