If it fits in RAM, you might as well put it in memcached. You will likely get a 10X speedup.

EDIT:

To be fair, RAM is cheap these days, and most real world projects fit into RAM without a crazy budget.

Why even memcached? It's not going to be 10x faster than your typical LRU cache (e.g. Postgres' shared buffers). It might scale a little better, but you should only consider that when it's worth it.

Ram is cheap everywhere but "cloud" instances. Was just noticing the other day, I can get about 128GB of ram on a dedicated instance for the same price I am paying in the cloud for 16GB.

Yeah, cloud prices are insane. I only rent individual servers.

Very few real world projects actually do need the cloud features. It's nice to have, sure, but you're paying a lot for it.
