I would recommend the newly available through official Pi channels,
oracle-java7-jdk...It is a full distribution of JIT'ed Java (including
Swing) with hardware-floating point arithmetic. I think the jdk8-ea
(early access) is a tiny bit faster but not complete (no Swing). I think
openJDK has not JIT.

I do lot of hacking on embed devices like Pi and BeagleBone for fun, I
run clojure mostly on ejre and it is much faster and memory efficient than
openjdk
compiled for ARM, but still suffers from startup time (in Pi case it actually
much worse).
Also ejre in development right now, so sometimes it crashes.
Things like drip are helpful, but still clojure.jar takes some time to load.
Also cached jvm can give you unexpected errors in rare cases.
I tried node.js but wasn't very satisfied with results.
Basically node.js can be much slower in some
cases, memory usage isn't ideal but startup time is good. I'm not big
fan of node.js as a platform, so I still looking forward to something
closer to metal (like yours clojure-metal project).

That's actually a major issue for those wanting to use Clojure to work on a
RPi or similar low end system. These systems are also so memory
constrained, that last I checked, the CLJS compiler wouldn't run too well
on them either. Now that doesn't stop people from using Node.js to run CLJS
code once it's compiled and copied to the device, but still, not exactly
the ideal solution.

For a tiny Clojure uberjar, startup time on my desktop is about a second.
Tolerable.
well, a tiny Clojure/Swing uberjar on the raspberry-pi (oracle-java7)
takes 9-12 seconds to start!!! not so tolerable...
in fact, in the absence of a splash screen, the user has the quite
convincing illusion that nothing is happening!!!
this of course doesn't mean anything, I just thought it is worth
mentioning...
