I don't really know about Evolution, but in general using real folders
_should_ be much faster. If your mail client has to do filtering and
sorting of mail, it has to download at least the headers of every mail
in the 'input folders' and sort them itself -- taking up valuable
network bandwidth, RAM and (possibly lots of) time.

If you do your sorting into separate folders at message delivery time on
the server, then your mail client doesn't have to download messages
which end up in (v)folders you don't actually want to look at, and in
fact your mail client doesn't even have to download headers for all the
messages in a folder you _do_ look at -- it only needs to have the text
which it needs to display on-screen, if you scroll the index display to
that point in the folder.

Vfolders, on the other hand, do allow you to have folders set up such
that a single mail could be in more than one folder -- it could be all
of 'Important' and 'From Fred' and 'Sender is Jane', for example. Using
real folders doesn't allow you to do that.
