What does your query file look like.  On of the biggest things  that 
affects the numbers for a caching server is the response time of the 
authoritative servers that answer the queries in your file.  Network 
bottlenecks can be a problem too.  (I remember one time I experimented 
with a caching server that had a stateful firewall between it and the 
Internet; effectively killed connectivity for everybody in the building)

You may want to look at resperf:

You may be able to get some more meaningful numbers from it.
