Hudson: Builds Taking More Time Than What It Takes, Running It Locally

I found unusual behavior on Hazon. Hudson's work takes about 25 minutes, where when I do the same work locally, it takes 9 minutes. What am I missing here?

I increased JAVA_OPTS, MAVEN_OPTS and even gave the server more memory to start with. The machine has 12 gigs of memory.

-Xrs -Xms1024m -Xmx1024m -Dhudson.lifecycle = hudson.lifecycle.WindowsServiceLifecycle -jar "% BASE% \ hudson.war" --httpPort = 9090 --ajp13Port = 9099

MAVEN_OPTS:

C:> echo% MAVEN_OPTS% -Xmx1024M -XX: MaxPermSize = 1024 m

JAVA_OPTS:

C:> echo% JAVA_OPTS% -server -Xms1024m -Xmx1024m

However, the assembly takes 25 minutes.
