I am definetly out of my depth here, but... Speaking of GCJ's JIT...

Sometime back, Ian Rogers here brought up the PearColator project at: 

I have been working on an open source Java based PowerPC emulator based
around a JVM's optimising compiler. If you have long running server like
workloads then I have found the performance is approaching QEMU fast
whilst having memory supported by a page based system. However, the
system is a lot less sophisticated - booting operating systems and being
a generic emulator is a distant reality. I have created a website at
http://www.binarytranslator.org/ or
http://www.cs.man.ac.uk/apt/projects/jamaica/tools/PearColator/ . I'm
sure some people would be interested in this and may feel like they want
to contribute. I'm happy to oblige and to share with QEMU. Thanks,

Looks like he's getting at least some tolerable numbers...

As I said above, I'm out of my depth here.  I just thought it was worth 
bringing this up in case people had forgotten about it.
