[MlMt] sluggist Mailmate - how to optimise?

[Jason Davies]

I accidentally have an update on this.


Firstly, OMM switching off 'Recipient headers' in 'Auto-completion 
Sources' did seem to speed Mailmate up, but it didn't speed *me* up 
because I discovered how much I rely on it;)

Switching in back on left me with some delays (but as I said, I think, 
I've improved my hardware and it's improved the delays). However at some 
point Mailmate just got locked this afternoon and after an hour I had to 
not only force-quit it but eventually force shut-down the whole mac, 
which wouldn't restart.

On relaunch, MM got very unhappy about the mailboxes and insisted on 
redownloading the entire lot.

Now, the sporadic delays are much less (three seconds, roughly).

All this suggests to me there are three related factors:

1. Heavy disk access needs good architecture
*and*
2. The archives perhaps become messy to access (and we can't run 
Diskwarrior on AFPS drives)

and 3. MM has to do a lot of work to look up recipients in a giant 
'sent' folder.

Obviously these impact each other; if 3 is irrelevant (switched off), 
you don't need such a fast machine or fully-optimised directories, and 
so on.

I'd be interested to hear from other well SSDed/RAMmed users whether 
this fits their situation.

cheers
Jason
