I think there have been a few required slow downs since those were done.

> When tested with openswan 2.4.11, I can only get at most 1.2Mbit/sec with esp-3des-md5 and esp-aes-md5 (using ixp4xx driver).  Without ocf, the throughput is around 500Kbit/s.

What speed is your IXP platform ?

We get somewhere between 35-40Mbps out of an accelerated IXP using
openswan. 

It sounds like you do not have OCF enabled for openswan at all ?
3Mbps is very slow,
