No, it's not. Mail.app (and probably Thunderbird) indexes the most 
important headers of the messages. MailMate really indexes all headers 
of all body parts of all messages including the often numerous Received 
headers. Some optional behavior might help here.

No, it's most likely that MailMate is sensitive to some set of 
conditions (fast/slow connection, number of messages, number of 
mailboxes, types of emails, etc.).

Yes, the Activity Viewer is very primitive. Note that if you click on a 
connection then the log of the connection is shown in the lower part of 
the window.

MailMate has to ignore server-side subscription states by default, 
because many users have unsubscribed mailboxes without knowing it. I had 
to make it an opt-in feature. But note that the “Edit Subscriptions” 
button can be used before adding the account. (If this doesn't work then 
it's a bug.)

You are welcome to contact me off list. I have a beta which should be a 
bit faster for the initial import. You could also help me with some 
sample reports when MailMate burns CPU, but I cannot promise you to make 
improvements soon.
