Watch it, Dude! Your process virtual memory saved in swap space should match whatever was on disk when you froze your penguin... If you're going to do bizarre things, then why not stop the penguin as-is without suspend and copy its primary address space, the vmdbk, the swap disk, the I/O's in progress, the timers set to fire... and the phone number of the local shrink in Endicott who signed an NDA with IBM :-) Really, look at what you want to achieve and do your experiments to verify the numbers. :anecdote type=funny. Some time ago I was sitting in a presentation where the vendor explained about his "luke warm" servers that were running along, ready to deploy the application that ran on a machine that died (key part of the HA configuration). The waste of resources for all these java agents waiting for their master was initially not understood (well, the server has nothing else to do but wait) and then justified by the time saved to boot Linux, so you only had to start the WebSphere application. The chap had to sit down when the customer told him the average server boots in 2-3 seconds to the root prompt, but WAS taking minutes after that. He started to ask about memory test and power-on self test, but the customer had pretty much lost interest in his solution by then.
