No doubt that this will lower the RAM usage somehow. Let me rephrase my
question: Any idea on what scale e.g. a doubled maximum_object_size will
lower the RAM requirement (in percent)? (Same with switching the
replacement policy).
IMHO RAM usage depends on the _mean_ object size, and this is not
directly configurable as it depends on the type of traffic going through
the machine. I think it is difficult to predict the RAM requirements and
thats why I would always start with a smaller cache_dir and add some
space later on while monitoring the RAM usage.
