[MlMt] What takes time at startup?

[Helen Holzgrafe]

Hi,

Also, if you have Apple's "Activity Monitor" (inside the 
Applications/Utility folder) running when you start up Mailmate, you can 
directly see that Mailmate is using 100% of your computer's available  
CPU cycles during its startup.

That's why a Mailmate Startup window that shows some form of progress 
bar, the name of each folder as it is being processed, or "25 of 300 
Smart Folders verified" or some other indicator gives the user faith 
that MailMate is actually doing something and not hanging. This window 
also gives some clue as to how long until MailMate is done with start 
up.
