Yes, with AES128 we were seeing about 1 Mbyte/sec (UDP transfer). With
AES256, 900 KByte/sec. This was Linux 2.4 + FreeS/WAN with the ipsec_algo
patch.

Yes, but I don't remember the speed we got. :)

I remember with net4521s doing wireless without encryption using PCMCIA
802.11b cards, we were seeing about 500-600 KBytes/sec (TCP). With 3DES it
was down to 250-300 KBytes/sec. Using a net4801 instead, you might be able
to get up to 600 KBytes/sec. I don't think I was seeing transfer speeds
quite that fast.
