Can the "Android Library Update" phase, somehow be sped up?

Question

Eclipse Galileo,
ca 20 Android projects, with many dependencies between projects
(util, testutils, one testproject for each library and app, whitelabelling etc)

When starting Eclipse the following is displayed in the progressbar:
"Update SVN Cache", - decent speed
"Android Library Update", - SLOW, with loads of network access
"Building workspace" - decent speed

Can the "Android Library Update" phase, somehow be sped up ?

Update 2011-06-14
I'm now running Eclipse Helios, Ubuntu 32-bit 10.0.4 vbox guest on Win7 , Android SDK all fully patched as of 2011-06-14.
The same issue remains, "Android Library Update" is slow, BUT now the CPU is 100% with NO network traffic.
Sooo... JVM tweaking may work, or running Ubuntu 64-bit 10.0.4 vbox guest on Win7 host with "apt-get install ia32-libs" as an alternative. No time to investigate either of those options right now though.

Here is how I tunned up my Eclipse install in the ini file:

-startup

plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.1.R36x_v20100810

-showlocation

-showsplash

org.eclipse.platform

--launcher.defaultAction

openFile

--launcher.XXMaxPermSize

512m

-vmargs

-server

-Dosgi.requiredJavaVersion=1.6

-Xms40m

-Xss4m

-XX:CompileThreshold=10

-XX:MaxGCPauseMillis=10

-XX:MaxHeapFreeRatio=70

-XX:+CMSIncrementalPacing

-XX:+UnlockExperimentalVMOptions

-XX:+UseG1GC

-XX:+UseFastAccessorMethods

-Xmx684m

Note I am on eclipse 3.6 and using jdk 1.6..

The other thing update to Eclipse 3.6..
