Out of curiosity, are you using basic_get, or basic_consume?  I've
found that basic_get has performance like that, whereas basic_consume
is at least 10x faster.  I'm also using persistent messages with
explicit ack (in transactional mode), and using Barry's python library
I get in the 1k - 10k messages/second range on hardware that isn't any
better than yours.
