The JDK1.1.7 port from blackdown does not come with a JIT compiler.
This will make it much slower than the Windows version which does
have a JIT compiler. You should also keep in mind that benchmarks

I was having this problem but one of the nice folks from the blackdown
porting team told me how to fix it. The fix was to add the libjava.so
file to the process space with this command.
setenv LD_PRELOAD libjava.so
After doing that it worked perfectly.
