Hmm, I didn't see any difference for MISSes when I activated the Solaris
"forcedirectio" mount option (since 2.6) which is said to transfer from
user memory to io without a kernel copy. But then, (a) it was a lab
environment and (b) I didn't look at the effects on HITs, because I was
banging an empty Squid.
Judging by what you explained on cache_mem, I should *not* use that mount
option, because the kernel buffer cache is actually my object store (for
larger objects)?
