I found a few more that can compile bytecode to native machine code.

JNC is just a graphical front-end to GCJ.

GCJ itself is not Java spec-compliant, so it would not be fair to use
it for performance comparison.

ARM Jazelle supports AOT compilation, but that's a Java ME solution.

I tried GCJ for this word counting program. It was slightly slower
than Jet and slightly faster than JVM. If -Xms64m flag is added to
JVM, which gains around 50 ms, then GJC and JVM were about same -- 670
ms.
