Hi,
It has been previously reported that Squid will never serve a cached
resource directly from memory once the resource has been written to
disk. In other words, cache_mem is allocated to in-transit resources
only, not "hot resources in general", with the particularly interesting
effect that all resources cached before restart are served from disk
after restart, no matter how popular they become.
Is this still the case in Squid 2.6 STABLE12? Comments in the config
file seem to suggest that this problem has been dealt with:
# 'cache_mem' specifies the ideal amount of memory to be used
# for:
# * In-Transit objects
# * Hot Objects
# * Negative-Cached objects
Thanks,
Ben
