Tagging and Relinking Super Slow

I suspect a new drive/RAID won't help you.  I think you simply have "too many" folders in a single folder and MC is slow to stat() them.

Go to Finder and go into your main music folder.  Look at the status bar at the bottom of Finder. It should say something like "2600 items, 768 GB available".  That's the count of how many files and folders, plus how much free space.

Can you tell us how many "items" you have in your music folder?

Thanks,
Brian.

This is the current file structure:

(EXTERNAL) HARD DRIVE > MEDIA (folder)

And then within the MEDIA folder the music is divided between 3 folders: HD DSF folder, HD FLAC folder and SACD ISO folder. So the music is divided between 3 folders. That's how I initially set it up to separate the different formats, but am regretting it now. So in part what I'm doing (slowly, it will take a while) is moving everything into just one folder instead of those 3.

And the total number of folders between those 3 is about 5000 folders. BUT remember, there are many subfolders within those many of those 5000. (Artist folder that has several albums by the same artist. But that's inconsistent. Overtime the cataloging got out of hand!)

blgentry:
It's probably a mistake to make one big folder. 

You should do some sort of organization that makes a smaller number of stop level folders.  It would be really nice to have it be less than 1000.  Maybe Artists could be the top level and then Albums under each artist. 

Unless you are saying that you have 5000 Artist folders.

Anything over about 1000 folders, at any individual level, is probably going to cause some kind of slow down.  The total number of folders going down the structure doesn't really matter.  What matters is how many files and folders MC has to touch at any given level.

This is an educated guess based on my experimentation.  My largest top level folder (Music/FLAC) has about 350 folders in it (they are named for Artist).  From the F6 > Browse dialog, it takes MC about 2 or 3 seconds to show the folders.

Typing in the Tagging Window is instant for me.

I do recognize that your collection is probably 10x or so the size of mine.

The biggest of the 3 is HD FLAC folder. That has over 3,000 folders in it. And many of the folders have sub-folders. You're saying that 3,000 is too much and should be broken down even further? Let's say have COMPOSERS A-D folder and then COMPOSERS E-J folder, etc.? That would obviously increase the number of top-level folders, but have far fewer in each. I'm not opposed to doing that... but is there an easy way to move this and re-link in bulk? (Well obviously moving is easy, but re-linking........)

And my collection is enormous. As a classic music listener, there are dozens and dozens of recordings of the Beethoven Symphonies, and then Piano Sonatas, and then imagine that for everyone. So yeah, the collection itself is huge. I plan to listen to it all when I retire!

blgentry:
Because this is new territory for me, I'm reluctant to recommend that you do a huge re-organization.  If the developers can confirm that my theory is correct, then a re-org would be the correct thing to do.

If or when you decide to do this, the RM&C tool can use Expressions.  Expressions can do calculations, like extracting the first letter of the composer name and things like that.  So, you could do some of these moves automatically.  If you were going to do this, I would start very small and do one album.  Then do several more one by one.  Then do some smaller groups of albums.  Work your way up so you can verify as you go.  But that's IF you are going to do this.  My theory might be wrong.

But even with a large classical collection, how can you have so many top level folders?  Are they all bare album names?  Because if it was by composer it would be a relatively small number (less than 50 I would guess).  If by orchestra then it would be probably less than 200.

Does Bob or anyone else from JRiver have any commentary on this?

Brian.
