Apache 2.0.43, Solaris 8, Sun E220R, 4 gig memory, gig ethernet. We tried both Sun forte and gcc compilers. The problem was mod_mem_cache was just way too resource intensive when pounding on a machine that hard, trying to see if everything would fit into the cache... cpu/mutexes were very high, especially memory was out of control (we had many very large files, ranging from half dozen to two dozen megs, the most popular of those were what we really wanted cached), and we were running several hundred concurrent connections at once. Maybe a new cache loading/hit/removal algorithm that works better for many hits to very large files would solve it I dunno.
We finally settled on listing out some of the most popular files out in the httpd.conf file for mod_file_cache, but that presents a management problem as what's most popular changes. It would have been nicer if apache could auto-sense the most popular files. Also it seems mod_file_cache has a file size limit but at least we got enough in there the disk wasn't bottlenecking anymore...
