real world testing of Redis as a bayes backend?

[Quanah Gibson-Mount]

Has anyone done any real testing of Redis as a bayes backend?  Talking with 
one of our customer, with a trivial <60,000 accounts, they are seeing:

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
22452 redis     20   0 28.7g  28g  740 S  9.6 72.4   1139:38 redis-server
28GB purely for a bayes DB for < 60k accounts is insanity.
