Tagging and Relinking Super Slow

--- Quote from: blgentry on July 26, 2023, 07:38:33 am ---I just did a few experiments with an HFS+ (spinning) drive I have attached to a Mac.
1. Created 3,000 files in a single directory. Then navigated there with Rename, Move, and Copy Files > Directory > Browse. It took about 15 seconds for MC to enumerate the files and show them.
A. Finder shows the files pretty much instantly.
2. Created 7800 directories in a single top level directory and navigated to them with RM&C as above. MC shows these instantly.
A. Finder shows these instantly.
3. Created 7800 files in a single directory and repeated. MC takes about 50 seconds to enumerate.
A. Finder shows the files instantly.
I conclude that MC is going to be "slow" enumerating directories with THOUSANDS of files in a single directory. But it is very fast with THOUSANDS of directories in a single top level directory.
Does the OP have thousands of files in a single directory?

Brian, thanks so much for doing all that! Here's more info on how my system is set up: I have thousands of albums, many of them in high resolution (so ISOs from SACDs and DSFs, but also hi-res FLACs, etc.) There is a folder on the external drive for music, but within it each album is located in its own folder, some times there are subfolders. So let's say I'll have Beethoven Symphonies - Karajan folder and within it more folders of the various recordings of Beethoven by Karajan. Etc. etc. etc. So there are several thousand folders total within the MUSIC folder.
Also one interesting note on the delay in tagging music: the drag only happens if I do it via the separate Tag window. If I just select a category within the main MC window and select F2 to rename - the renaming happens right away. But within the Tag window - it is extremely slow.
As far as the Finder via MC taking extremely long time to open folders - that I don't know what to say. I'm just rearranging and renaming a some folders for easier organization, and from MC - it takes extremely long to open a folder. If I just open any window on the external drive via my regular Finder (clicking in directly into my exteranal drive from the desktop) everything works instantaneously.
I'm attaching a screengrab of what the the F6 window looks like if I am relinking an album to a new location (these options were pre-selected, I did not make these choices.) Is there perhaps a different option I could be using?

An external drive may not perform as well.

I'm clearly a luddite on a lot of this stuff! But - is Finder pre-indexing files every single time I open it? Shouldn't it index it once and then retain the information? But this is what happens: I've moved some recordings of Bruckner conducted by Blomstedt into one source folder (they used to be scattered.) So now there's: Bruckner - Blomstedt - and within it are multiple folders of the various recordings he has made. I relink one album to the newly renamed/moved subfolder. Then I go to relink the second album and try to go back to the original Bruckner - Blomstedt source folder (which Finder already opened a minute ago), and it still takes a minute to open it again. So the indexing doesn't seem to be sticking. It seems to re-index every single time, even folders it just opened.
DmitryB:
To give ya'll a visual idea of what my source folder looks like, here's a small section. Folders with subfolders in them for each individual album. In each subfolder, only one album.
blgentry:
Your top level music folder, which opens when you do Browse from the Rename, Move, and Copy files screen... It has thousands of folders. But are there FILES in that top level also, that are all by themselves?
If it is just folders, or just folders and a small number of files, then my experiment does not seem to apply. I'm not sure where to go from here.

I've done a little more experimenting. This time I created 26,000 directories (a-z, 1-1000 combined). Finder loads these in about 15 seconds the first time and instantly thereafter.
MC takes about 3 minutes to display the list of directories. This is clearly something with what MC is doing for each file or directory before it lists them.
Now the other issue, where changing metadata tags is slow...I don't know why that would be or if it's related, but it would seem to be.
I would suggest that doing file moves might be done better directly with MC. Tell it where to move your files instead of "relinking them" after the fact. For simple moves this will be easier as it is one step. For big moves (hundreds or thousands of files), you are probably best doing the actual moves with Finder (or a similar tool) and then "relinking" in MC as you have been doing.
Bob (or other MC programmer): Why would changing metadata be slow? Does MC have to traverse the path of the file, doing a stat() at each folder path along the way? I wouldn't think so, but why else would it be so slow to do a tag change?
