Also I changed default for new folders to mbox.
The point of mbox being faster is that you don't run whole a bunch of routines that will open file, read a 1-2 KB, and then repeat that file after file. Modern hard disks transfer speed is something like 50 MB/s, so for the biggest mbox that has old mails from opensuse list and is 500 MB, computer needs 10s.

If I repeat the same command: time cat main > /dev/null

KMail always needs 35s to switch to that folder, which means that it doesn't use copy already present in memory. I haven't checked kde4-kmail.
Whoah, that's pretty miserable! Thunderbird uses indices that speed up switching folders a lot. Though I am using imap, so I can't compare it to local storage. On my setup I have about 5.8 GB in my personal mailbox (via imap on server). In my case it is a Cyrus imap, that I plan to switch to dovecot in the future. Changing folders takes at most a few seconds, even if the folder contains more than 40000 mails. Though I can understand that for a personal mailbox on local storage mbox is indeed a better solution than maildir. The I/O to access the mailboxes is much less than for maildir. -- Sandy List replies only please!
