Effect of very large number of shortcut characters

Hi

Could someone please explain what the effect of configuring a very high number of shortcut characters would be in terms of space usage on Exchange and EV?

If I have a shortcut character number of 10,000, EV would still go through the archiving process for each message and change the item to shortcut, but what would be in the contents of the savesets of those email with less than 10,000 characters?  Would they be almost empty, but still occupy the miminum cluster size on disk?
