1500 workstations / 600 servers. I'm currently testing it on a test
subnet with around 50 workstations and have been wondering about the
cache stats. dnsmasq: time 1372247969 dnsmasq: cache size

insertions re-used unexpired cache entries"??

for the clarification Simon, i was wondering if the cache was correctly
If i understand you correctly it means that when the cache is
filled, newer queries won't be cached as long as a cached one has not
expired, right ?
Any drawback to max cache-size value to 10000 ?
