Initial scan taking too long [#21916]

[SgtPepperman]

It's me again

Due to some Google Drive antics on my files, I programmed MM 2024 to scan my files when I first open the program as you can see:

That first scan is taking now about one and a half hours. That's something never happened before.
I'm using MM 2024.2.1.3200

This is my database configuration:

EDIT: Returned to 2024.2.0.3184, and it does it quite faster (about less than 1 min). I'm going to stuck with it in the meantime.

I'm also getting very slow scans in 3200, this was not happening in earlier betas. Used to be much, much faster.

This is expexted due to a change how Artwork is scanned. This is still being fine tuned for a final 2024.2.1 release.

This should be resolved in build 3201. Can you confirm that it works for you?

Yes, much improved.

Test folder contained 10,788 files and 3200 took 18 min 36 sec to scan. Same folder in 3201 now takes 3 min 28 sec.

The test folder is one I haven't changed anything in for quite sometime and the 18 min scan was a re-scan from a couple days earlier. I did not note the time on that first scan, but it's where I first noticed the scan time taking much longer.

Given the size of my collection (+100k tracks), it takes a while, but it reduced to about 45 min to 1 hour (which I personally think is still quite long), so definitely there's an improvement there on 3200.

For 100k I see that very reasonable. As it is dependent on storage speed where the file is and system resources. I dedicated 20 cores to Scan that speed things up a bit.

If you want compare MM speed test then Copy those 100k tracks to different folder on Same HDD and see how much it would take plain copy to work.

Re-scans of folders with little or nothing changed since the previous scan used to be MUCH faster before the 3200 & 3201 releases. Which is when I first noticed the increased scan times. 3201 is much better than 3200, but still not like prior releases.

A first time scan used to take a while, as expected, but the re-scans were much faster before.

I do agree with tmf. Scan was very quick before the update.

I can confirm this. With around 60.000 files a rescan takes maybe 20min instead of 2-3min.

What MM version takes 2-3min to rescan 60k for you?

I just timed it with 57.294 flacs:

Build: 3194
Time: 25sec

Build: 3203
Time: 45min

I just timed it with 57.294 flacs:

Build: 3194
Time: 25sec

Build: 3203
Time: 45min

25sec for 3194, that seams impossible, I tested with Windows CMD DIR /S on my folder with aprox 80k and just listing took >1min.
Also can you please start re-scan on 3203 and leave it for 5min and save the log file. It should show us what MMW scanned in files and why even it is not complete.

I Started rescan of My NAS files that I know that are not changed and will see after three iteration an average re scan time.

Please include if you're doing an update scan or scanning in files for the first time and included scan settings, particularly your scan settings for files already in the Library and if you're analyzing for duplicates and if you scan file directories for Artwork.

I use a SSD PCIe 5 as a bootdrive and a raid-drive for data, maybe thats the reason the scan with build 3194 is that fast.
