Sync with Lightroom CC is really slow. Does Adobe throttle the downloads?

Before anyone asks, I have a 1Gbps fibre connection at home and there's nothing that's hogging the bandwidth at the time I left Lightroom Classic to sync the Lightroom CC photos. I've also been monitoring the network download speeds and it seems that it's just constantly at 50-100KB/s. Which would take "forever" to sync up just a single album of 380 photos (4GB in total).

4GB files can be downloaded in about 3-4 mins tops sometimes at 20-30MB/s on my Internet connection... so waiting for almost 3 hours to see only 154 photos synced is really painful. Is anyone else also facing this issue?

Bump. Interesting, more than 2 years later I have much the same problem. My LrC library had got pretty messed up, so I thought as an experiment I would download a new catalog from scratch from the cloud. It was also a way of testing how the backup worked. In have 60k photos taking about 250GB. My hard drive has more than 1GB free and I have a download speed in excess of 200 MBps.

The sync was going on for a week and then stuck at 1449 to download for over a day, I did a "rebuild sync data" and it got back to syncing about 1,200 pretty quicly, but now is again moving at about 1 photo an hour.

Anybody any ideas, or find out any more about this issue?

2024, same problem. Network engineer, understand all the data transfer problems people bring up as a reason. LrC going about 8-56 kbps on my Mac downloading synced files from Adobe cloud 275GB in photos total. Lightroom desktop client (CC) did the entire download in less than 2 hours on the same laptop on the same internet. I've tried reinstalling, rebooting, new catalogs, everything. Adobe just really seems to want this to run at 1995 dial up modem speeds. 2Gbps connection BTW, works flawless for everything else. 10Gb networking all the way to the modem. Most recent version of Mac OS, lightroom classic.

You’ve posted to an ancient thread. It is highly unlikely that the issue described in this thread, though not impossible, is the same one you are currently experiencing. Rather than resurrect an old thread that is seemingly similar, you are better off posting to a new thread with fresh, complete information, including system information, a complete description of the problem, and step-by-step instructions for reproduction.

If you have a 1 Gbps connection and it is symmetric, you should be able to get 100 MB/s downloads consistently but you might never see it as most raw files are smaller than 100 MB and most download measuring tools have a time constant of 1 second or higher. You should see it when downloading big psd or tif files or video. I can easily saturate my home 200Mbps connection with Lightroom CC downloading at 20 MB/s for such big files which is really the max it can do and at work (fibre connection) I get more than that.

One detail: are you talking about uploading images or downloading? Most connections, including most fibre ones, are very asymmetric and have upload speeds an order of magnitude smaller than download. So if you are talking about syncing images up to the cloud, you might be running into the limit of your connection even with gigabit fibre. My home internet, while 200 Mbit/s download is only 6 Mbit/s upload, which is the very max I can get where I live without paying for a new fibre line to be installed (indeed a very costly proposition)

If you are talking about download from the cloud or upload with a symmetric fibre connection, Adobe does not seem to throttle their connection as far as I can tell so my guess is that something else is not right with your connection.

Internet speeds can only go as fast as the Slowest part of the path from server to computer.

No matter how fast your home connection is and no matter how fast Adobe's connection speed is if there is a bottleneck someplace then that is the fastest you can upload or download.

You are syncing with the WEB system and not directly to LR CC, Whatever version, Desktop or Mobile

So what exact version are you writing about when you say LR CC, Mobile or Desktop?
