|Embedded system startup time [message #875576]

I am involved with building an embedded system using Virgo Tomcat. Our basic OS (on an Atom processor, running Linux) boots very quickly, but it takes several minutes for our application to start up.|
The app is based on Virgo Tomcat, and I am looking for guidance as to how we can optimize startup.
For instance, it seems that the 'work' directory is rebuilt from the ground up on a reboot. Is there any way to preserve the contents - a sort of 'suspend' mode, or is this behavior inherent in the way Virgo Tomcat works?
Also, is there a way to determine which artifacts are, or will be needed? Any way to prune out or defer some artifacts, or is that list already optimized by Virgo Tomcat?
I'm looking for a factor of 5 improvement, and I don't know if it is reasonable to shoot for that, or if we are attempting to misuse a 'big iron' software stack on a low-horsepower embedded system.
Opinions, suggestions, etc. are all welcome.
