Java stored procedures. Are they slower than PL/SQL?

I have created my first java stored procedure and it seems very slow. I use it to move a large amount from a load table to main tables. In a previous design we used PL/SQL procs and this load took about 8 hours. Based on the number of rows that loaded before I left tonight it looks like the JAVA proc will take over 20 hours. Why the HUGE difference?

Is there a way to speed this up?
Are the java procs compiled or do they use the just in time compiler?

Thanks,
