Importing messages from Mail via AppleScript may not be fast enough
my highly scientific estimate* is "a couple of messages" a second.
Importing someone's entire mail archive would take a long time.
I just did a test and it's quite fast if you ask for all the messages
at once:
[...]
I'm seeing average times of one to two milliseconds per message (e.g.,
7 seconds for a mailbox with 4,660 messages) on a 2.5GHz Quad G5.
Don't forget to process the standard mailboxes as well - for some
reason they're presented as properties rather than elements of Mail's
'application' object, so you have to deal with them separately.
Also, one caveat with getting entire messages: if you've got any with
large attachments, that will slow things down, e.g. OMM [1]:
Importing 9 messages from Drafts
Total: 0.4956 Average: 0.0551
Importing 184 messages from Inbox
Total: 2.6736 Average: 0.0145
No messages found in Outbox
Importing 1609 messages from Sent
Total: 59.5408 Average: 0.0370 <-- some attachments in my Sent mailbox
Importing 122 messages from appscript
Total: 0.3417 Average: 0.0028
Importing 66 messages from personal
Total: 0.6233 Average: 0.0094
Importing 1139 messages from read
Total: 8.2016 Average: 0.0072
Importing 73 messages from ruby
Total: 0.8477 Average: 0.0116
Importing 237 messages from work
Total: 67.6088 Average: 0.2853 <-- lots of attachments in my work
