Re: [ACRYPTO] New asynchronous crypto layer release.

[David McCullough]

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
