For this matter, I disabled sorting setting:

$config['message_sort_col'] = 'None';

But don't see any performance impact.

Also enabled cache like this:

$config['imap_cache'] = 'db'; // false
$config['messages_cache'] = 'db'; // false
$config['imap_cache_ttl'] = '30d'; //10d
$config['messages_cache_ttl'] = '30d'; // 10d
$config['messages_cache_threshold'] = 1024;

This account has 12GB, and many many emails, about 60.000 in inbox, and not
counting the ones in the folders.
Is there something else I can do?

Accounts with low quota or emails are fast showing emails/login' in.
