Java Linpack Complaint

Does anyone benchmark Java apps any more? I'm specing a server for purchase and need it to run Java fast, and our PostgreSQL database, fast. Sun has offered a sweet discount on their servers, but they still don't compare in price to Dell. At the end of the day, I'm asking myself, how much CPU can I get to run my app fast?

So googling for some benchmarks, I found this Java Linpack List of Timings which provides an applet based test that measures Java's floating point performance on your computer.

My Toshiba Tecra A4 laptop, which I do nearly all of my development on, has a 2.0 GHz Intel Centrino processor, and 2 GB of ram. It scored differently on different runs, with the median being right around 270 Mflop/s.

If that sets the standard in "my world", how fast will my app run on an Intel Xeon 5130, or an AMD Opteron 2210? There are no good published benchmarks!
