Brion-
At the moment we don't exactly have a lot of free
memory floating around
Larousse seems to still have about 400 megs free, pliny 885, that is, used
by Linux for caching, but Linux always grabs as much as it gets for
caching -- that doesn't mean it has any substantial effect. For example, I
have 640 MB of RAM, "free" tells me that 620 are used -- but minus
buffers/cache, only about 200 MB are used.
Using an application-optimized cache like memcached would be orders of
magnitude more efficient than relying on Linux' kernel-based caching.
