Thanks for the tips - I will keep that in mind.

for your scenario; one instance will do just fine. (one instance is
preferred to keep the number of connections down, and so that client
libraries can better optimize multi get requests)

also many on this list (myself included) would recommend you not
"guess" at how much memcached memory space you actually need, but
start with something small like say a few hundred megs of memory
(memcached is really efficient) and grow it as you need while watching
your usage stats.
