PowerBook Performance for Java Development?
brasten wants to get to the core of this issue: "I'm in the market for a new development notebook. I would like to jump into the Apple world and pick up a PowerBook. However, compiling very large Java applications of course takes some time, and so raw processing speed is a factor. I have been unable to find solid data on how fast a 1.33GHz PowerBook runs against the modern x86-based notebooks. Does anybody have any information that could help me compare?"
The G4 can't win the battle against modern x86 processors anymore.
But on the other side, how often do you compile a whole project? While you develop, there are mostly only very few files changed. Compiling them then is only a matter of seconds. On every platform.
The much more important question is, if Mac OS X and the applications can speed up your developing process? If you saved 10 seconds by faster editing the source files, you can spent 5 seconds for the longer compilation time and save 5 seconds for your personal recreation ;)
