Hi,
We're trying rock cache for the first time, on squid 6.13. The machine is
quite large and heavily used, with 10 workers configured, 140G of shared memory
cache, and 500G of rock cache configured. However, the cacheNumObject SNMP
counter is staying quite steadily at around only 570 even as the cache grows.
Currently du shows the rock file taking 40G, and the mgr:storedir statistics
show 448k entries.
Does anyone have any ideas about this for us?
squid.conf is attached.
Dave
