MemcacheFS

It looks like others have had similar thoughts - lighttpd have a
mod_memcache module which caches small files in memory for faster
access.

http://trac.lighttpd.net/trac/wiki/Docs%3AModMemCache

"Serving several thousands small files for lighttpd is quite
challenging. Operating System has to do a lot of random access, which
increase io-wait. mod_mem_cache is the plugin which stores content of
files in memory for faster serving. It's more configurable than OS
buffers (at least, linux buffers), in some cases yields better
performance.

For example, you can configure it to cache files smaller than 5 kb, just
cache files with a specific mime type or different strategies to free
memory when the configured limit has been reached."

Thanks,
Rob.
