ResourceScalability

How does NetBeans scale with available resources like memory size, CPU power, number of CPU cores, I/O speed? Can features use the extra resources for better performance?

Effect of memory size

Measured on WinXP SP3, JDK 1.6.0_16, Netbeans 6.9 20100615, limewire j2se project. Startup and scanning are cold measurements.
