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.

has anyone called Adobe and talked with them about this issue? Just curious of a response if so! I uninstalled my 6 and went back to 5.7. When u got 80 sessions to edit, 6 ain't getting it done for sure! EPIC FAIL ADOBE

I was able to chat with a guy a couple of days ago who said Adobe is aware of the problem and are working on a fix. He suggested switching back to 5.7.
I'm with you on the insane slow down from 6/CC. Made it unusable for me.

What really ticks me off is that Adobe isn't coming forward with any info openly. And why haven't any major organizations (NAPP, for example) commented either?

Among all the speed problems I also have a big problem with the library module. If I hold the arrow key for any more than a millisecond it starts scrolling uncontrollably for about 10 seconds completely making me lose my place. I just downgraded to LR5. I have an i7 4770 with 20gb RAM and SSD but working on d800 files. LR5 wasn't fast but 6 is just unacceptable.

The same here :-( My system is pretty OK: 16GB, i7-3970K @ 4 GHz, SSD Evo 840 & HDD black caviar, GTX 970.

This lag kills all my passion, creativity and motivation for perfection. :-( I await for the last day of deadlines for Post-production :-(

GPU acceleration? To what? Viewing? I need DEVELOPMENT module to be fast as thunder. Local adjustments most importantly. I tried everything including starting a NEW catalog.

Filtering of photos - awful. I use GOOGLE PICASA for primary review and deletion of bad photos. Even imported pics when zooming for quality check on focus awaiting 2-3 sec.

On a huge amount of photos - it is painful.

ADOBE better STOP introducing NEW features!!! Work on PERFORMANCE!

Just to chime in here, I'm finding CC very sluggish

6 core MacPro, 24G ram, and SSD's throughout

Much slower than 5.7.1, I frequently get the spinning colourful wheel of death (which is does recover from but didn't get it with LR5)

Haven't seen much point in upgrading to CC so far, I hope Adobe issues some serious updates shortly

Good to hear that. Actually I wanted to change from the Mac Pro 2008 to the 6 core model but it seems like a faster computer does not help

Just for the record..... same problem. I'm relieved to hear I'm not the only one. I was kinda getting bummed out that my 6 month old Macbook pro couldn't handle LR6 yet it ran LR5 like a dream. I'm anxiously waiting for this update.

I also find Lightroom 6 ( I use stand alone version ) much slower than v. 5.7 I am scanning slides, which is 80MB each 48Mbit TIF and exports as jpg.

I have two pc ́s
1. Intel Pentium J1900, 4GB, Win 8.1.
Lightrooom 5.7 was usable even on this low end PC. Lightroom 6 is unusable. Development changes takes long time (especially if involving more pics), import and export takes forever. Export of 97 pics took 1,5 hour. Meanwhile the PC is unusable for other tasks.

2. Intel i7 4. gen, 8GB, Windows 8.1.
Lightroom 6 can be used, but sluggish. V. 5.7 runs very smooth with no special delays. Exporting takes takes long time, and meanwhile the pc is almost unusable

I've found all LRCC is slow. It needs a performance improvement.

I've found the same; pausing face detection and address lookup seems to help. The long pole on the import function is converting to DNG; it seems to take longer to convert. Since I don't have a 5.7 version any more it is hard to test the difference.

My system (IMac, 10.10.3, 3.06 GHz Intel Core 2 Duo) takes ~ 32 seconds/image to import, convert to DNG, and build standard previews (2880) of Fuji (RAF) files. According to the Activity Monitor, both cores are running flat out to do the work.

So, Adobe has a senior engineer commenting like crazy over on the PS windows hidpi scaling forum. And yet here we still have nothing - not a single word - from Adobe. And nothing so far in the industry media about this.

Adobe, if you are reading these posts, PLEASE join in the conversation.

The LR team has been very, very busy since the release - they just haven't had time to respond to all the topics (and I wouldn't either if builds didn't take so @#%$@#% long).

Given the continued issues, I've removed the "not a problem" flag from this topic. It sounds like some systems do have serious performance issues that need further investigation.

Hi Chris, thanks for commenting. It is appreciated. Adobe needs to hire some people to do this kind of go-between work instead of seemingly relying on you for all of it.

From the user perspective, the lack of regular feedback (or initial feedback in this case) is really worrisome (as I'm sure you realize). We all rely on LR as a major tool in our workflow (read - livelihood) and to have such a serious issue really does negatively impact our lives, as sad as that may sound.

I had a shoot yesterday that required delivery today and taking into account the number of images, had I used LR CC instead of 5.7 I literally wouldn't have been able to fulfill my contractual obligations. With Aperture gone the way of the dodo LR really is the only app available. No pressure...

But open, honest commenting about what's really going on - even when it's simply acknowledging a serious problem exists, goes a long way towards easing friction and lowering customer anxiety.

We have some people with that sort of position, but they're swamped with other things at this time. The LR engineers have replied on some topics, just not all topics.

Just to be clear, you're saying Adobe is both too busy to tell it's customers that its flagship photography app doesn't work properly and too poor to hire someone to write a message and send it out to subscribers/purchasers? I'm really trying to give you guys the benefit of the doubt here, but you're not making it easy.

The LightRoom team is quite busy right now.

Chris, I don't think anyone necessarily needs an engineer or programmer to give us blow by blows. I'm actually quite glad the LR engineering team is busy. I'm sure we all are. That said - and I hate to sound snarky - the project mangers should have created some sort of mechanism for communicating with the customers some time back in the 1980's. There should be a client relations team. Other companies have been known to create things like that. If the LR team really is too busy, and if Adobe really doesn't think it has an issue in the way it handles these sorts of major release snafus, then the problems go far deeper than a lousy software release. Perhaps it would be even better if software engineers weren't the ones handling these customer interactions. The constant refrain 'everyone at Adobe is too busy to help you' is more than a little insulting.

You know what, I'll do it for Adobe (free of charge). Just cut and paste this on your site then put out on an email blast:

'To all our loyal customers, we are sorry to report that Lightroom 6/CC, in its current version, has major structural flaws. As such, we strongly recommend not upgrading from version 5 until such time as we can solve this temporary problem. We sincerely apologise for this unforgivable delay in admitting the problem and will be offering a rebate to those whose businesses have been negativity impacted by this situation.'

Last thing - Chris, I do appreciate you engaging. My frustration isnt directed towards you.

Well said, Denni.

Adobe main concern for sure is the communicating part... I am pretty sure we all got out of the nerdy state of the 80s & 90s and now we all use computers and we all know how to communicate.

Obviously someone @ Adobe is still along the old ways ;-)

There is a bigger problem then the heading would lead you to believe. I'll say again. I bought a new machine just for this version. i7, GTX980, 32 gigs, NEC 30 II, on and on. I started this machine up and installed the old (5.7) and then "LR6" and had problems out of the box...there is a problem for sure. I'm also about to take my LR certification as soon as they make up the darn new testing schedule. I understand that there's a problem a little more then most. Many of the problems I've seen have nothing to do with "working in the background" (although a problem). Something I never do BTW. But if I load up the software with a multi layered file I can kiss it goodbye after a while. I also work with OnOne and PS. I'm talking 10-15+ layers. Say its on a virtual copy. If I go back to the original copy it "may" work fine and not slow down. There are multiple layers of problems. So...you may use LR "lightly" and not see a problem and say>>>>"well I don't have a problem" but when you push the program...it does. I went onto another person's system with the same file I had a problem with...then started to do the same work on it. After a while....poof...there you go. It bogs down. Different system but it still loaded up and slowed down. Guessing something to do with the way the cache/ram from card is handle...beyond me though. As ealier...my solution was to just start a new Cat. in 5.7 CC till they fix. 5.7 works perfect on the same machine....same file that was merged into LR6 CC...works perfect and lightning fast.

I did have somebody say that they talked to a rep and that person said there is a problem for sure. But that is second hand. I feel sorry for all the people that are struggling and trying to fix it and Adobe will not acknowledge and just lets them keep on looking for a solution that is not there. That is the part that really seems to suck. I'm lucky...I have 5.7.

I wrote a letter to the Adobe CEO and told him to withdraw this awful product from the market and apologize to the user base.
