OK, now I understand the situation. You're complaining about folder
opening time. This is not related to filtering at incorporation nor to
processing stuff at start-up.

Now, if the folder you're entering to has no processing rules, and that
incorporation doesn't get triggered while entering folder (try entering
File/Offline mode, THEN enter the folder), then you have a real strange
slowness here - I can't yet explain why.

What filesystem type your mailbox is located onto? I hope it's not a
vfat stuff connected thru USB2.
