I would be interested in having this subject clarified again.
I'm playing with 3.1.15 and I have not configured cache_dir. Hence,
all my
hits can only be from memory.
Look at those numbers for example (very idle system, I agree):
You can see no storage but still 99.6% of the hits are marked Disk
hits and
0.4% are marked as Memory hits.
Can someone please help me understand the numbers here?
There are many types of hits. REFRESH_UNMODIFIED, IMS_HIT, etc. most of
these are not separated out from a generic "all hits" statistic.
MEM_HIT is only the hits served from memory which required no
validation or special handling. The label "Disk hits" is a bit
misleading.
NP: if you are actually getting "TCP_HIT" specifically in the
access.log that would indicate there is still a disk cache_dir
somewhere. Or a bug in the label marking, which is not unsurprising
since the labeling system is a bit old/fragile.
