How to speed up RCP application build time?

Hi,
The build time of my application it too big. Every time I try to build
and run it it takes around 3 minutes to complete the build task,
sometimes it takes more but I've never had to wait less than the 3
minutes.

I noticed that the task that takes longer it the "Generating
information for Auto Update...", can I disable it? Or what else can I
do so that in order to test a small change I don't have to go and get
a cup of coffee, I'm spending more time in the coffee area than on the
project :)
