fill rate?

Hi all,
Just a short query this time ;-) We have a cache which seems fairly
un-stressed during an actual run (low cpu and disk utilization), but
only achieves poor to average hit-ratios at the rates we'd expect.

Would it be seem reasonable to think that the fill rate is set too high
for this cache?

We are currently using 75% and would expect to see good performance from
this box at 75-100 reqs/sec minimum; however, although response times
and errors are fine, we don't get near the target hit ratio until we
bring the rate down to 25 reqs/sec.

Thanks,

Bryn
