-For the default Blowfish cipher the optimal value for the 'tun-mtu' parameters for a link between these two servers now seems to be '''36000''' bytes, although the difference for higher MTU sizes is minimamal. Also note that the performance numbers are nearly identical to those generated using the system OpenSSL 0.9.7e library.

 When using the AES-256 cipher there is huge performance gain. The optimal MTU value now is '''48000''' bytes, but overall performance increased by a factor of 2 for nearly all MTU sizes.

 Now an '''iperf''' result of '''930 Mbps''' is obtained, which shows that performance is not so much limited by the division between kernel-space and user-space processes, but mostly by the encryption and decryption routines as found in the OpenSSL libraries.
