As you have probably seen, there has been a lot of threads on this topic.
It was addressed at SWW2011 and supposedly it going to be addressed in SW2012.
We shall see. SW2011 (I am personally not using it yet) I have heard is suppose to be
better at handling the memory and releasing it better. I am not seeing that according to posts
like this one. I think this one is a good one to keep for future reference.
I think there is a difference between the file size Jason is talking about and the improved memory handling "promised" in SW2012. I think SW2012 is adding to the improvements supposedly made to SW2011 regarding releasing system memory back to the operating system.
Thanks for the link. I can't wait to get back to the office and take a look at the SW file structure on some of our parts and assemblies.
