Lightroom 6 / CC2015: Very slow UI response with background export(s) running

Lightroom 6 / CC2015s UI reaction is very slow / sluggish when a background export is running. When three exports are running, the development module becomes virtually unusable.

In Lightroom 4 or 5 it was no problem at all to start up to three or four background exports - of course the UI, especially the development module, was considerably slower than normal, but definitely completely usable.

LR Version: CC 2015.0.1 (with 6.0.1 update), on Window 7 64. Processor is an i7-2600, there is 16 GB RAM. RAM does not seem to be exhausted, LR6 uses about 3...4 GB with 3 parallel exports.

Edit: It makes no difference whether GPU usage is turned on or off.

I don't know what has happened but over the past few weeks my workflow has diminished tremendously. I can't even work on photos at this point. Simply switching photos at this point is causing a problem.

So frustrated right now. I've been using Lightroom for years and never once had a problem.

What the did you guys do with Lightroom?!?

i7, 8 Gb Ram, plain Intel HD Graphics 4400
After upgrade from LR4 everything went so slooooowwwww (and even slower)
Went to preferences/ perfomance and disabled the use of GPU.
Now faster and similar to LR4 performance ... which unfortunately aren't tremendous.

I will add my frustration to the list. It seems like I can work on about 6 images, either in Library or Develop mode, zooming in at 100% of check sharpness, then when I go to the seventh image or so, it spends loads of time loading the next image...sometimes several minutes. And this despite the fact that I built 1:1 previews on import. It is becoming unusable. i think I'm going back to 5.7 until they fix this. Even grinds to a halt when I select multiple images and try to add captions.

Windows 7 Professional. 16 Gb RAM, i7, 64 bit

Has Adobe even acknowledged this, or is it radio silence?

Yes, Adobe reads all the posts in this forum.
And the Lightroom team is busy working on solutions to many of the issues posted here.

Then Chris, why oh why, is what you just wrote the first -and only! - written acknowledgement from Adobe?

Because there are multiple topics going on about issues, and the LR team is kind of busy fixing issues. I post on here while I'm waiting for compiles to finish, or stuff to download.

Chris, don't take it personally but you really should be cautious about commenting here on problems as an employee of Adobe.

The people responding to this thread are by and large industry professionals whose lives are being impacted as a result of this problem. Responding to questions, especially ones like this, belittling our complaints and reminding us that the LR team is busy isn't helping and I'm fairly positive that your customer service team would have a conniption if they knew you were here commenting on issues without providing an ounce of customer support.

My life is literally impacted right now because of this. I estimate my losses are already topping a thousand dollars simply because I cannot process the photos I need to process. I process over 500 photos a week on average. This week I've gotten through 50 before my frustration reaches max. It's bad.

While I appreciate and respect your position within Adobe, I believe you should have a bit of perspective when communicating with people on forums like this and understand that we're not 12 year old kids complaining about a product.

We're professionals. This is my career that is being affected by this. I cannot afford this and I certainly can't afford to have Adobe ignore my plight.

I imagine I'm not alone on this.

So, with all due respect, I honestly could care less that the team is busy with other problems. This is my problem and there are dozens of other peoples on this thread alone who have acknowledged they are having the same problem. Many of the people on this thread have indicated they are also professionals and they are also suffering loss of business as a result.

Would your advice to us be to contact Adobe for some monetary compensation, or do you want to go tap your boss on the shoulder for us and have him contact someone so we can get an official response here?

That is great news ! Hopefully they will come up with good solutions.
Is there any formal Adobe reaction to the many complaints ?

I'm fairly positive that it has nothing to do with hardware. The two computers I use for processing photos were built by hand, purposed for editing specifically. They're rendered worthless after less than 10 minutes of use.

My Macbook, which I've used without a problem for the past year, is a complete waste of time to even consider using now.

It's definitely not hardware.

Strip 1 (Mirroring) can improve reads, but never writes, they equal basically that of a single drive.

I can't even select four images to group caption without it going in to a minute long "calculating" session.

I am having the same problem. Since updating to the most recent Lightroom version, any action, especially export, slows EVERYTHING done.

ok.... so.. did they patch something because today my Lightroom is flying... working without a hitch, acting like it did on the first day.

I've done absolutely nothing. I opened my macbook and started editing and it's perfect...

I see no difference in performance and i'm on it every day. i've not seen any updates come thru creative cloud so there may be perceived changes. I will say turning off face detection and address lookup helped a small bit a while back, but once the database of faces is built, it shouldn't have to run on anything other than new imports. hopefully we'll see our first patch soon...

I want to go back to 5.7 and I am wondering the best way to do that. I have my old catalog. Do I simply open up my LR 5 catalog and reimport any photos that were added after the upgrade? Will the edited xmp files work in LR 5.7 or will I lose any edits made on the files in the meantime? I have close to 20,000 new images that will need to be imported and I really don't want to lose the work I've already put into them.

Any suggestions from anyone would be greatly appreciated!

Hi Michelle, most of the edits should be fine, but not the elements created using the new tools (like dehaze). Well - you'll still be able to access those edits in camera raw (access through Bridge), just not in lightroom 5.7. Your metadata will still be there, including keywords, labels, ratings, etc.

And ya, just open your old catalogue and add at current location. Turn off file renaming and any metadata additions in the import dialogue. Maybe don't do 1-1 previews yet - at least not for the 20,000.

I installed lightroom 6 last week and using it today it was very slow. Wouldn't even load thumbnails.

I found that version 5 hadn't been uninstalled and the short cut I was using pointed to the old version. I did an upgrade and my expectation was that LR5 would uninstall and be replaced by LR6

Now I am actually running version 6 - all seems well.

Hope this helps someone else

Without question Lightroom CC 6 has some major software issues when it comes to exporting images and speed! I'm so glad I found this thread that proves this is not an isolated case or a hardware issue. I can only hope for an update in the very near future to resolve this issue.
Example: currently as a write this piece I am exporting 115 raw files @350 dpi and saving as a JPEG. Exporting files from an external Thundetbolt RAID drive and saving images to a USB thumb drive. In the past (using the previous version of Lightroom) I could do this in less than 5 minutes. I have now surpassed the 1 hour mark (just about complete) WTF!
I'm running a 2014 MacBook Pro; SSD, 2.3GHz i7; 16GB of ram. Using same 5D MK III, same in camera settings, same SD cards, same settings in Lightroom; ....SAME EVERTHING!...and getting ridiculously slower exporting results.
Adobe please resolve this issue ASAP

Mark, thanks for the operation details and the time. I can tell you that your machine's behavior is not typical. I just duplicated your test as best I could on a 2012 MPBR 16 GB of Ram.

115 Raw files from Canon 5d MK III Saved as JPEG, native size at 350 pixels per inch. Catalog images on internal drive. Saved files on internal drive. Elapsed time 3 Minutes 4 seconds to completion.

Since I don't have a Raid Drive handy to test, I can't duplicate your details exactly. If you don't export to a thumb drive but export to your Mac's internal drive instead, what is the time elapsed?

This is the second time I see DPI mentioned. When talking about saving to a file DPI is useless information. The size of the file, or the dimensions of the picture expressed in px, would give a better idea. Having said that, I suspect that the size of the exported picture is more dependent on I/O speed then on LR efficiency.

Rikk,
I also have a non Raid drive USB 3.0 drive with even slower results. This was not an issue with my he previous version of Lightroom. Using either external drive. Side note: slightly faster when saving export to MacBook Pro SSD and then dragging and dropping images on to thumb drive.

Two Lightroom thoughts:

1. Preference file - have you tried resetting?
2. Uninstall/Reinstall?

Rikk,
Two valid questions and no I have done neither of the two due to the fact that I just stumbled upon this thread just a couple hours ago and wasn't sure if others were having the same issues. I'm pretty certain that my preferences are most likely set to the default settings but I will have to check and verify.
The uninstall / reinstall would be a simple solution and any easy fix ..... If it works. Willing to try anything at this point.
