So doing some checking. I. Trying to sync Classic, and after watching stats for three days now, I can say that it’s downloading 96 files per hour.There are 23,590 files to go. So sometime this lifetime I should have them all...My connection here is fibre optic, so what is Adobe’s connection? Wet string.Come on guys. Invest in some infrastructure.

Please send us the diagnostic log and the system configuration you are using for further investigation.

Hi there,
Thanks for getting back to me. I've attached the Diagnostic Log, just generated now, with 7,742 files to go... :-)

I have put the log on my own website, because I can't see how to actually attach it to this message.

Now let's see if I can also include the system config.

Lightroom Classic: Release 8.2. Camera Raw. 11.2
Lightroom CC: Version 2.2

MacMini. July 2012
OSX 10.14.4
2 TB Storage (1xSSD, 1xHDD)

Modem Status: Connected
Traffic Type:PTM
Line Rate - Upstream (Kbps):20000
Line Rate - Downstream (Kbps):48999

Sky FibreMax.

If there is anything else I can help with?

Thanks for looking into this.

Hi Robert,
Thanks for the info. Are you trying to sync down the files that are uploaded from LrCC or LrWeb?
And what is the size range of the files that are being downloaded?

Hi there.
I set up LRCC, and imported all my photos into it, tidied it up and became familiar with it. All worked well. All files synced to the web and Cloud perfectly. Quite quickly. I also store all images locally on a built-in drive I have just for that purpose. 

I checked on the Web interface,, that all was in place. I am able to share galleries etc from the web interface and so on. Perfect.

Next, I opened LRClassic and created a new Catalog. Blank. No images at all. I set it to sync with the cloud and set up the Location for Lightroom CC ecosystem's images. I pointed this to an independent folder on an external drive on my Mac. Opened Preferences and the Sync started after a few moments.
At first, it went quite quickly, and I thought, "Great, this is going well". It didn't last. Within an hour it had slowed to a crawl.

The total sync finally finished the day before yesterday sometime. From the day I first sent this post to March 3rd. The last day, I was still watching it, and it finally sped up again a little.

Anyway, it's all done now.

The Lightroom CC Local Store gives an indication of combined sizes. This is the folder for 2019 so far. Also its location.

Individual file sizes range between 20K and 20M across the years. Some MOV files that are agenerally larger, but not very. Different cameras, different formats. jpg, png, dng, raw. and 162 mov files. 2004 to 2019.

The Lightroom Classic ecosystem folder looks considerably different. ????
214 GB compared to LRCC's 5GB.

How exactly it turned 5GB into 214GB, I'll leave for you to figure out :-)

I have done no editing or importing of any sort in Classic. Nothing. Just watched it sync. In theroy, it should be a mirror of the LRCC one I'd have thought. And visually it is. But it did take a LONG.... time to get there.

With Classic open, this is the System Info as generated by Classic.

Hi Robert, thanks for the detailed information.
From the images that you shared, we can see that the 5.36GB folder contains 332 images where as 214GB folder contains 46,700 images. You can go to LrCC or LrWeb to check the actual size that is present in cloud. Please let us know the total size present in cloud.
If the images are uploaded from LrCC/LrWeb to cloud and downloaded to LrClassic, then the sync is expected to be slow and we are working on it.

Hi Suhas,
Actually slight misunderstanding there in my last message

The Actual Pictures folder for Lightroom CC is this.

211GB. The Actual LrClassic directory is 213GB So I'd expect there to be some slight difference because of the way it handles files.

What the size is on the Web I've no idea. I can't see where it tells me the actual storage size.

However - All seems to be working now,
except that there are four (4) images that won't download.
They seem to be stuck. Just sitting there and not downloading at all.

Thanks for your information
Best regards

You can Click on LR Symbol there, then go to Account Info. There you can see the actual size on cloud. 


Please send the current diagnostic log(where you have 4 stuck images) which helps to investigate the issue.
