RE: WDSC

["Mark Phippard" <MarkP@xxxxxxxxxxxxxxx>]

FWIW, things should be a lot faster when WDSC 5.1 comes out later this 
month.  I have been using WSAD 5.1 and it is much faster than 5.0 was. 

There are two primary reasons:

1)  Eclipse base has moved from 2.0 to 2.1 and there were a lot of 
performance optimizations made.

2)  IBM is now including a new JVM that they are using to run the IDE. 
This JVM is called the J9 JVM and was originally developed for small 
embedded systems.  I am not sure of all of the details but it provides a 
noticeable performance boost.  For example, the IDE starts in about 5-8 
seconds on my machine instead of 45-60 seconds with 5.0.

So for those two reasons alone WDSC 5.1 should be a lot faster.  The 
announcement also mentions that they are using caches more in 5.1 so 
hopefully things like program verify will also be a lot faster.

Yes, this is the Java Virtual Machine.  If you plan to use WDSC
throughout the day, the best way to do so is to leave it running.  That
way, you only need to start the JVM once.  Also, WDSC likes lots of
memory, at least 512MB, and I usually recommend 1GB.
