[UM-LINUX] libgcj Performance?

[Edmund Kohlwey]

Hi,
I'm doing a research project this Spring which is based on some work 
that I've done for my job recently. The research project itself involves 
visualization of large graphs/networks, and as such has involved some 
OpenGL programming. I've already got a large codebase which is in Java, 
and I was hoping to reuse it for my research project. I am, however, 
concerned about performance of the JVM, and I've had trouble finding 
information about the Sun JVM's performance vs, say, libgcj. Does anyone 
know anything about the performance of libgcj (or any other native code 
java compiler) vs the Sun Java VM? Perhaps someone could recommend some 
resources to investigate?
