Back then the unhappy user was using a 1 GHz Pentium M notebook. I tried 
this again. Guess what, the latest Eclipse Helios (3.6.1) took 3.5 (!!!) 
seconds to start up the whole Java workspace, open few projects and fully 
initialize the editors etc for the most active project. Has the original 
complainer ever used Photoshop, CorelDraw, AutoCad, Maya/3DSMax, Maple/
MathCad/Mathematica, or some other Real World Programs (tm)? These are 
all fucking slow. That's how it is: If you need to get the job done, you 
must use slow programs.

My hardware specs: Core i7, 24 GB of DDR3 RAM, Sun Java 7, x86-64 Linux 
2.6 (a middle range home PC with some extra memory, that is)
