you're still missing some basics about java memory management. In
another thread, I mentioned the java VM will take more memory than it
needs, that is because it prioritizes throughput over footprint. There
are knobs for all of that. It's not clear what's taking so much memory,
but it's certainly not luminus or clojure. Use jvisualVM to find out
for sure instead of comparing apples to oranges.

On OS X Mountain Lion I just compared the memory footprint of 3
out-of-the-box web apps in these frameworks:
Clojure/Luminus: 152Mb (JVM) + 186Mb (main) = 338Mb
Ruby/Rails: 62Mb
Elixir (Erlang)/Weber: 32Mb
I was rather shocked, to say the least. Not to troll, it has made me
think again about deploying Clojure web apps on hosting platforms
with modest amounts RAM. I'm sure the figures for all 3 would
increase significantly once the web apps are fleshed out but that
probably applies equally to all 3 frameworks.
