Lightroom CC: Very slow sync speeds with a large import

As I'm migrating from Aperture I moved ~50Gb of images into LrCC in one import. Images import to library fine, but the sync to cloud is incredibly slow - Task manager shows it topping out at ~0.5Mbps, whilst a quick speed check while the sync is running suggests upload speeds 15-20Mbps.It has been syncing for a few days now (admittedly not 24/7) which is pretty annoying! Any suggestions on how to get this going faster are much appreciated!

Having slow sync problems too! Trying to sync 400 photos for a full day and only 50 have synced. Would upping my internet upload speed with my provider help? Got in touch with adobe and they say there’s nothing wrong with my Lightroom cc. Does the age of my iMac have anything to do w it??? Help!!!

Hi David, go to https://www.speedtest.net and select a server on the US west coast, and then tell us your download and upload speeds. It does sound like an internet speed limitation.

Having the same issue.  Been trying to upload 1TB (35,000) photos for almost three weeks.  I still have 5521.  My upload speed is 34.4 mbs.  Working off of a 2017 5k iMac.  Now that you know my specs, what do you recommend?  From what I've read this seems to be an issue with the product itself.

adobe cloud doesn't have per client speed to 34mbps/sec. Some complain about 1.5-10mbps/sec so it will take 3x-30x as long. Your upload should take 3days and now it can take 30 days. If this is for business I can help you look at performance uploads so you can figure out this issue (hourly services). If you need faster cloud storage then I can help with cloud storage solutions.

Same issues here, high bandwith everything is ok, syncing takes up ALL of my bandwith, but 1 photo takes 1 hour to upload!!!! WHAT is going on here??

Syncing 20k photos since I'm evaluating switching to Lightroom. Started last weekend. 5 days later, 4k of the photos have uploaded. Activity Monitor shows lightroom sustaining less than 1MB/s. The speedtest.net site shows ~70Mb/s.

This does not bode well for when I actually want to shoot photos and edit them the same week.

MB does not equal Mb. Also, I’m assuming you have 70Mbps DOWN, but what is your upload speed? This is the factor limiting the sync, I’ve found. I’ve recently upgraded to 20Mbps UPLOAD and it’s syncing great!

The uppercase / lowercase distinction was intentional. I have 70 megabits per second down. I guess that would be around 8.75 megabytes per second down.

You're right, though - up speed is clearly the limiting factor in a sync :) I ran speedtest again and it looks like I have around 4Mb/s up. I guess that's only 1/2 MB/s. Probably why my sync is so slow. Sigh. I guess I have to call comcast.

Thanks for pointing that out

Hello. I recently (a few days ago) migrated my 260GB of images to Lightroom CC. This went fairly quickly and as I would expect. Now I'm on my new machine and I want Lightroom CC to download the masters to my local machine. The downloads are extremely slow and it seems like they Lightroom is somehow downloading in short bursts (see attached screenshot). How can I speed up this process? I think that this is an unacceptable performance for an application and service that I pay for quite a lot of money every month.

Test it on a different network (ie. hotspot your phone) to confirm that it's the application and not some QOS running on your router.

Hi. I could narrow down the problem. I had my download location for the master files configured to be a folder on my Synology NAS. Lightroom CC came to a complete sync stop after about 120GB of downloaded data. At the end it became completely unusable and I couldn't even change application settings anymore. As soon as I could somehow manage Lightroom to use a local folder things started to work again. Lightroom moved about 5GB out of the 120GB to my local drive and then started downloading masters again at full speed.

As a sidenote. My WIFI is very fast and I normally get about 720MBit/s upload speed to my NAS. So I can say that my network certainly is not a bottleneck. I found peopel having similar problems in this thread: https://feedback.photoshop.com/photoshop_family/topics/lightroom-cc-syncing-issues-when-originals-ar...

Internal upload is a different kettle of fish! You didn’t mention the local NAS. This topic is about syncing with Adobe which seems to be very much affected by limited upload speeds to Adobe’s servers.

SO it seems as this problem has been around for 2 years, and nobody answers - I am having the exact same issue now - 2TB of pictures, I can't even grasp how many it is, but they need to be migrated - and it is taking forever! If I am lucky I get 10 GB transferred per day. I am up to about 300 GB or so now, and have been working at it for over 2 weeks. I am about to give up... any thoughts!?
