I just ran "openssl speed" and on my very modest Athlon XP 1700 machine and both the aes-128 and blowfish ciphers clocked in at approximately 60-65 megabytes/sec throughput. That's about 50 times faster than the theoretical maximum throughput of 10Base-T ethernet. Even this modest system can encrypt 5 times faster than the absolute maximum rate of 100 megabit ethernet. I think you are vastly overestimating the CPU requirement of encryption. And it is also why the original poster should not waste his time trying to find a nonexistent, useless, and insecure option to disable encryption.
