A few ideas:

- give more memory to the VM
- Try JRE 1.5
- try the server VM (-server)
- Optimize your XSL-FO
   - Make sure you make use of property inheritance
   - Avoid unnecessary properties and nested elements
   - Avoid tables
   - Avoid page-number-citations
- use JPEG images instead of SVG
- use Type 1 fonts instead of TrueType fonts
- Buy a stronger single-processor machine. FOP cannot make use of the
second processor if you're only rendering one document at a time.

Good luck!
