I haven't, but do know some hints.  Make sure that you have a machine
w/ AESNI, AND make sure you're using AES-GCM or AES-CTR..  Using
AES-GCM is best as it avoids using a costly auth algorithm, as the
AESNI instructions provide instructionts to make the GCM (auth) part
of AES-GCM faster.

AES-GCM can run at over 1GB/sec on a single core, so as long as the
traffic can be processed by multiple threads (via multiple queues
for example), it should be doable.
