I use Oracle JDeveloper (free as in beer:
http://www.oracle.com/technology/products/jdev/index.html) quite a bit
and I've not noticed the problems that you have other than taking a
'long time' to start, maybe... Certainly no more than any other very
large and sophisticated IDE. JDeveloper is written in Java.
JDeveloper includes a code profiler that will help you write better Java
code. When the developers finished the code profiler they ran the
JDeveloper product code through the profiler and got a pretty noticeable
improvement in performance.
There are more than 6000 Oracle Applications (Oracle Applications,
Siebel, PeopleSoft, and a bunch of other companies we've acquired over
the years) developers at Oracle who are using JDeveloper and they all
want their tools to run fast. They wouldn't be happy with the kind of
performance that you describe below.
Not only that, but the developers who write the other tools at Oracle
(Portal, XML Publisher, BPEL Designer, etc.) all use JDeveloper, many on
Linux.
My own personal experience:
I've got a 1.6GHz Pentium laptop with 2GB of ram and I'm able to run the
below in quite a usable manner:
Windows XP Professional base operating system
VMWare image with the following:
Windows XP Professional OS
Oracle Enterprise Edition 10g
Oracle Application Server Enterprise Edition 10g
Oracle BPEL Process Manager
Oracle JDeveloper
That's a LOT of software to run on a 2GB machine.
I've also run JDeveloper on a Linux VM running X and didn't notice the
kind of performance you are describing below.
JDeveloper is a great big huge Java program that you can download for
free... Want to give it a try and let us know what you think?
