Overclocked for Netbeans 5.5
With a processor clock of 1.70GHz and a pair of 256MB DDR PC3200 (200MHz), Netbeans 5.5 will never be an IDE of your choice especially if productivity concerns you. It runs on top of the Java Virtual Machine using the Swing Tool Kit which is a bit heavier compared to what Eclipse is using.
Since I prefer using Netbeans 5.5, a desperate move would be maximizing the use of the CPU’s core speed.
Here’s a validation from CPU-Z:
CPU : Intel Pentium 4 (*1) CPU Arch : 1 Cores - 1 Threads CPU PSN : Intel(R) Pentium(R) 4 CPU 1.70GHz CPU EXT : MMX SSE SSE2 CPU Cache : L1 : 12/8 KB - L2 : 256 KB Core : Willamette (0.180) / Revision : D0 CPUID : F.1.2 / Extended : F.1 Freq : 1953.28 MHz (114.9 * 17)

My CPU runs at 1.9GHz now. I just increased its Front-Side Bus clock to 114MHz and there’s a big impact on Netbeans’ performance.
P.S.: Thanks to Betelgeuse for the correction 
A total lie. They are both written in java and as such need a virtual machine to run. One of the bigger differences between the two is the graphics toolkit used. Netbeans is built on top of Swing which is written in java and Eclipse is built on top of swt that is a thinner layer on top of gtk on Linux. The performance differences most likely have more to do with the code if the IDEs themselves.
