In EagleFiler it's best to merge the .eml files into mailbox files so that you 
have one file per group/folder rather than one per post:

Aside from helping with the filesystem issue, this also lets EagleFiler apply 
various RAM and index optimizations.

Keep your source mailboxes clean & not too big.

Because MM is so focused on "Smart Mailboxes" and de-emphasizes the 
on-server IMAP folder structure, it is easy to get into a situation 
where you've got thousands of messages in a source mailbox (maybe 
INBOX, Trash, a singular Archive mailbox, or maybe others as well)
and as a result also have thousands of message files in a single 
directory on your local disk in the tree under ~Library/Application 
Support/MailMate/Messages/.


Guilty as charged, though I don't have nearly as many messages as some 
folks here (and I do clear out Trash on a regular basis).


This is not as big of a problem as it would have been in years past 
because Apple has made advances in handling large directories over the 
years and we often have humongous filesystem caches in memory making 
recently-used stuff really fast, but this isn't just about your Mac. 
MM does work in the background keeping its cache in synch with your 
IMAP server and while your Mac may have the full metadata for the 
50,000 messages in your Trash in the filesystem cache because you keep 
trashing messages and never empty it, your IMAP server has dozens of 
people doing the same thing and it dumped your info out of the cache 5 
minutes ago when Joe Smith needed to scan his 100k-message Archive 
folder on the same server. So remember to empty your Trash. Delete 
mail from publicly-archived lists like this one periodically. For old 
stuff you want to have archived but don't need instant access to, use 
the Export command and delete it from the server. I don't know exactly 
how badly Apple's HFS+ performance declines as files/directory rises 
these days, but it is inherently worse than linear. I try to keep my 
folders below 2k messages and that seems to help prevent excessive 
beachballing.


FWIW I've been experimenting with archiving newsgroup posts (as .eml 
files) in EagleFiler and on this Mac mini things started getting slow 
and beachballing at something like 100,000 posts.  One simple answer 
there is to split them into separate EagleFiler libraries, e.g. work 
related groups / general interest groups.  Alternatively splitting it 
into folders by year might help at the OS X file system level.


Another answer of course is to get a more powerful Mac, preferably with 
SSDs ;.)
