In order to know if the new computer is any faster I clocked my current machine. There are quite many ways to do this. For me, development in Java is one of the few performance-critical tasks (and ripping of CDs).
I used the straightforward Scimark 2.0 benchmark. My result is not very impressive. I ran the benchmark while all my normal apps were running (such as web, email, winamp, etc). That's close to 50 processes, almost all idle but still... CPU was at around 4% when idle.
I use a Dell Optiplex GX260: Pentium4 2.26 GHz. 640 MB of RAM.
