Hello, I am messing around with an ordered collection of a class wich contains a matrix. As it the size grew I started to wonder if my code was something one should not do or if one would maybe outsource some data. I don`t know if it`s just in the RAM if iI start the VM. In that case i would overkill it at some point or not? So i thought of storing the data on harddrive to be able to recall it later when I need to but get it out of the running VM for the moment. Maybe you can enlighten me regarding this. In this picture you can see that my data is basicly stored inside of a inspector at the moment. So it would be cool to store the whole thing on harddrive. <http://forum.world.st/file/t371759/inspector.png> -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
