Well, you realize it's going to be a tradeoff, right? You don't get 
something for nothing. You could tune some combination of max-cache-size 
and/or max-cache-ttl/max-ncache-ttl/cleaning-interval to reduce the 
memory footprint, but it would trade off against CPU usage, network 
usage and/or query latency.
