Have you tried profiling the application on kaffe to see where the time 
is spent? It might be some inefficient library method that burns all the 
time, but we haven't found out about it yet.

A second thought: If you run kaffe without jvmpi, does that change 
anything to the better? It *may* (but doesn't have to) be the jvmpi 
support slowing things down.
