But re-sorting by message index shouldn't be very slow, since we don't fetch any data from IMAP server. I still force to not use this 'default'

Sorting ~30,000 threads with ~60,000 messages in them takes in the order of minutes on my machine. This is unacceptably slow, that's why I added the 'default' option.
But my point is to not sort anything if sort_col=date. We don't need 'default' sorting, since THREAD result is already sorted by date. I don't know what sorting are you talking about.
