Question - tmpfs for caching

eramba writes to a cache (eramba_v2/app/tmp/cache/) after a modal (page is loaded) the first time and will consume that cache (in theory, this is handled by cake) as needed until something changes on the modal (add, edit, delete) or the cache expires (every 5hours).

we played a bit with mounting a tmpfs filesystem on that directory (disabled swap completely) and we did notice some speed improvements, has anyone played with this? cake has a native memcache option which we might turn to use.
