I'm not an expert but maybe::
- you're testing IPv6 intentionally? AFAIK it's not been converted for 
MPSAFE (SMP)?
- you're testing localhost intentionally? Also AFAIK, something similar 
(too coarse locking?) is true for localhost and many benchmarks show it.

You'll probably need to test over real hardware to get gains for SMP.

Of course, I'll be happy to be corrected by someone who works with these 
systems :)
