However, there is kind of a design "idea" that it should work with 3GB of RAM. That would require significant kernel tuning, because few of us have any experience with machines that large. We have avoided or fixed terrible algorithms like O(n^2,3,4) stuff. We still have stuff that can be improved, but we are making continual progress. -- John dyson@freebsd.org jdyson@nc.com
