I have, in the past, used memcached + TileCache to cache Mapserver data
-- see http://tilecache.org/ for more information about TileCache. It's
not particularly well documented, but a user came to me the other day
and told me they are using it in production without problems. 

In general, I use disk-based storage, because it's faster than memcached
until you have enough machines to make a memcached cluster reasonable,
and there's more of it than memory. However, all my data 'lives forever'
-- we  don't have anything with high temporarl differences -- so I'm a
special case.
