If they are large, there isn't much that can be done.
FYI, the problem is that the messages are stored in the standard Unix mailbox format.
This means that if you delete the first message in a 100 megabyte file, IMail has to
create a new 100 megabyte file (minus the size of the deleted message).
I've got a 20 megabyte mailbox that I keep adding mail to (old IMail messages,
actually!) and that happens quite fast. So does the deleting of messages from
mailboxes that aren't huge in size. Of course, I rarely get large attachments, so it
isn't an issue for me (the timing is based almost entirely on the size of file, not
the number of messages in there).

The "back" button on browsers doesn't make sense in a world of dynamic web pages.
Originally, the "back" button would simply return the cached version of the page
(which isn't acceptable for mail, since it might display old mail, for example, that
had already been deleted). Sometimes the "back" button will go to the last past that
was requested, but attempt to refresh it (which still is no good for mail, since the
URL to "Delete message #2" shouldn't be retrieved a second time!).
Really, users shouldn't hit the back button. I do it sometimes (such as when I reply
to a message, and want to go back to see the original message), and usually it works
O.K. But, sometimes it doesn't. It's something you have to accept. This isn't just
a web mail issue; it is an issue for lots of types of dynamically generated web pages.
It might be possible to suggest to the browser what to do (use a cached page, or a
refreshed page), but even if you could, it still probably wouldn't work with all
browsers.
