http://httpd.apache.org/docs/2.2/mod/mod_mem_cache.html has a note at the
beginning stating that "In most cases mod_disk_cache should be the preferred
choice. This is explained further in the Caching Guide. In particular, this
module's cache is per-process", but in this note and in the Caching Guide
(http://httpd.apache.org/docs/2.2/caching.html#inmemory), the text is not clear
about the ramifications of mod_mem_cache being per-process.
The comment at the end of issue 39454 by Ruediger Pluem on 2006-05-01 09:56:05
PDT (https://issues.apache.org/bugzilla/show_bug.cgi?id=39454) gives a good
idea about this.
If the documentation can add just an additional sentence to make it clear that
if mod_mem_cache is to be used instead of mod_disk_cache, the recommendation is
to favor lower number of processes and higher threads per process so that
mod_mem_cache can work efficiently since multiple cached copies will most
likely result in the machine's memory, one for each process.
