Lightroom Mobile sync is too slow

Lightroom sync is too slow. I'm trying to use Lightroom Mobile for iPad and I started sync for collection that has ~8000 raw images from Canon 1Ds MKIII and 5D MKII. Lightroom is synching for almost 8 hours so far, and it is somewhere around 6500 images. I have 100/50Mbit connection and quite powerful PC, therefore, I believe, Adobe / amazon cloud service is a bottleneck. I'm located in Finland and I can see that us-west-2 amazon servers are used. Would it be possible to fix it? Otherwise, Lightroom Mobile feature would be useless for photographers in EU.

Can you go to www.speedtest.net, pick a server on the west coast of US and post what the upload and download speeds are please?

I choose few servers in CA, I get ping ~220ms, down: ~8Mbit, up: 6Mbit.
I briefly checked what ligthtroom process is doing and it uploads something to amazon servers, but speed is around 20-50Kbps,

There is a lengthy discussion on Adobe Forums http://forums.adobe.com/message/6281828 on the very slow sync rate for this product and lack of speed of processing on device.

Not sure how some are raving about it when clearly users are not enjoying the experience! The Kelbyonline intro lessons must be edited as I wait 5 to 10 seconds, as I scroll to the next photo, for the edit tools to become live!

Currently I am just pleased that my CC subscription makes the App free as I would be very disappointed to have paid for it.

How can you set it for offline?

Tap the 3 dots icon on the collection thumbnail and then select Enable Offline Use

Victoria - That is a lot more responsive! I thought this occurred by default .... now flicking through is quick and sideshow very usable. Only sluggish behaviour are the edit 'buttons' that do not activate for each photo for 3 to 5 seconds when moving through. Is this an issue with processor in my original iPad Mini?

Yes, I started testing on an original iPad mini and then the retina mini came out - the sliders are almost instant on the retina one but were sluggish on the original. The original iPad mini has a much slower processor, equivalent to the iPad 2, if I remember correctly.

i have already used lr for iPad, but not used it for some time, so far it has taken about 6 hours to sync, this seems an awful long time, anyone any suggestions and how can I tell how much it has already done or if it is stuckĀ

I work full time and run a part time wedding photography business. I was so excited about the potential time saving with the iPad version. Yeah, I thought, I can do all of my image selections on flights for work. I have been trying to images on this for two days, and out of approx' 4,000 images to sync, I have about 350 that actually have. WTF? I really do hope this improves, otherwise this is just a novelty joke of a product. Come on Adobe!

Mark, same question applies. Can you go to www.speedtest.net, pick a server on the west coast of US (i.e. San Jose) and post what the upload and download speeds are please?

It will help Adobe determine whether it's a problem at their end or a limitation of your internet connection, and therefore what they can do about it.

Does anyone know if you can sync photos by connecting the iPad to the PC with a cable?

No, you can't Mark (at least at this point in time) At 0.83Mbps up, I'd expect it to be taking around 30 seconds a photo, so taking 2 days to upload 350 definitely sounds like something's wrong. It may be because everyone's suddenly uploading, but they're Amazon S3 servers so I wouldn't expect them to get bogged down.

I am in Australia. I have a 15Mbit/1Mbit speedtest result local server. If using west coast US I have 5.95/.77 speed. I'm not sure how to find out what adobe servers I'm using. But whatever the issue the speed issues needs resolving because currently the product isn't worth buying. Having an option to local sync would be excellent. Adjustments in post processing don't take long at all to sync.

Sure Australia is a long way away from many places. But Adobe this product is near useless...

100 mbps downstream 30 mbps upstream - still takes me several hours to sync 200 photos.
This has been an issue since the introduction of LR mobile.

I use the iPad version to quickly review photos and swipe up or down to keep or discard. Much faster and more enjoyable process than on desktop - but the sync is killing me!

If the smart previews is 2,5MB each, then with 200 photos, I should be syncing 500MB of data. I can upload a 500MB video to youtube in a minute or two, so obviously it is not an issue with the connection on my end.
