Re: [SM-USERS] server-side sorting

[James S. <ja...@be...>]

Just to be on the safe side I reinstalled courier-imap (upgraded to 1.4.3)
and reduced the number of messages indexed in SM to 25.  I created a
subfolder of INBOX named ARCHIVED and move 600 messages there leaving just
shy of 100 in the inbox.  Here's what I've noticed:  Loading the INBOX
takes a considerable period of time if there are over about 100 messages in
it.  Other subfolders of the inbox, like my sm-users folder, which has over
a 1000 messages, load up almost instantly.

I don't think it has anything to do with the new sort/thread view.  I have
about 15 filters plus 20-odd message highlights setup in my SM options.  I
don't know exactly how this all works, but I think it has something to do
with the filters.  When I load the INBOX, I think SM applies the filters to
_all_ messages currently in the inbox.  By reducing the number of messages
in the INBOX, it speads things up because filters are only applied on those
messages.

Does that make sense to you?
