    This is a recent code fix they did. Unfortunately, the F5 itself can't handle
    much more than 200 conn/s anyways. The rainbow cards do not do the bulk
    encryption/decryption of packets. That's left for the general purpose
    CPU to do. At 200 conn/s the F5's cpu is pegged at 100% utilized.

    And you also want it to handle all your non encrypted load balancing too.
    Not much CPU left for that.

    It's a serious flaw in having the SSL accelerator inline with all of
    your non SSL traffic.
