I don't know about the "perfect" hit rate, but here are some stats
from one of my caches:
Count % Bytes % Status
------- ------- ---------------
0.09 0.01 ERR
0.09 0.01 TCP_DENIED
40.94 19.68 HIT
19.60 11.59 TCP_HIT
7.78 0.28 TCP_IMS_HIT
2.12 0.65 TCP_MEM_HIT
0.35 0.03 TCP_NEGATIVE_HIT
11.09 7.13 TCP_REFRESH_HIT
58.96 80.30 MISS
57.13 78.06 TCP_MISS
1.84 2.24 TCP_REFRESH_MISS
That's over a 24-hour period with 535 hosts making 129082 queries.
