Charles,
I did the test with the converted Bering-Contivity yesterday. I ran the VPN as AES then changed to 3DES and ran it again. AES was 6% slower. Any ideas why this would be the case?
I'd have to look at the code...I'm somewhat familiar with the 'stock' FreeS/WAN stuff, but haven't checked out the algorithm patch that adds the additional encryption options to SuperFreeS/WAN.
The only thing that comes immediately to mind is optimization. 3DES performs so pitifully that most architecturs have hand-optimized assembler stubs for the 'guts' of the encryption routine. If the AES routines are generic C code, it would likely explain the performance difference.
