Lightroom 6 Render Very Slow

I have recently upgraded to Lightroom 6 and have found that rendering previews takes about twice as long as Lightroom 5. I have an iMac with 5K Retina display and Lightroom says the GPU is enabled in settings. I'm just wondering if anyone else is having the same issue, because I thought this version of Lightroom was suppose to be faster.

Just checked and it's already off, well disabled due to errors. My problems seem to be more related to the new people module e.g amending the names of tagged faces is taking forever and my whole screen turns black and it takes about 10 secs to complete each amend. May be an idea to just not use this new functionality I guess!

Lightroom LR4 - very slow Keyword set updating

Lightroom LR4 - very slow Keyword set updating 1] keyword an image with some keywords from a keyword set. Those keywiords are highlighted in keyword set 2] select next image 3] wait about 4 to 5 seconds for highlighted keywords to be non highlighted. ARRGHHH the problem with this, is that yo ucannot use the keyword set to apply these keywords to the newly selected image until they are not highlighted any more. yet another area where lightroom is Slooooooooooow!!

Hi John, Did you solve the problem of slow update times associated with entering a keyword tag? I too am having this problem. During my most recent keyword entry it took 45 sec to add "Arizona, Hacienda Del Desierto, Lucy's Warbler, Spring " into the "Keyword Tags" box. During this time the box indicates "working...". The time to update has been getting progressively longer.
I have LR4 4.4 and I'm running on a 3.1 GHz IMac OS X 10.8.4, 16 GB RAM.
Regards
Ian

Lightroom is very slow, utilizes 100% CPU, then freezes or closes program. How do I fix it?

I am having a problem with Lightroom 5 being very slow, utilizing 100% CPU, then freezing or closing the program. How do I fix it?
I just upgraded to LR5 from LR3 on Sunday as well as CS6 from CS5 (which I have not tried out yet). I spent several hours talking with Vamil, from LR Support Staff yesterday. He was extremely helpful and kind and tried everything he could think of while remote-handling my PC and talking with me on the phone. He deleted preferences, cache, temp files, updated graphics with a new replacement file from AMD site, then re-downloaded and reinstalled LR5.
It is still very slow and then freezes and closes down with a message of utilizing 100% CPU. Within several seconds of using the brush in Develop, I started having lots of problems. I could not even move the picture around. The side screens would not disappear like they should. And I could not move to another picture. The day before I spent several hours trying to work on just 1 picture. After all the changes yesterday, I tried to move from picture number 1 to about 130 after having not touched it for 10 minutes, and a half hour later, it still said, "Processing" with no picture coming up, just a blank prieview pane.
LR Support suggested I get a new CPU though he thought according to specs mine should be ok and other programs were running fine.
My PC is only 2 years old.
I talked to HP briefly about CPU updates for my HP PC. He said I probably do not have a problem but suggested I run self-diagnostics and maybe buy a new CPU anyway.
I ran diagnostics listed through the HP Support Assistant connection on my PC. All was ok.
I still researched if I could buy a compatible CPU upgrade. I cannot even find any CPUs still selling that are listed for my PC. Best Buy Store said they could not even order a compatible CPU. They said my Bus speed may not be big enough, so they suggest I get a new PC. What Bus speed do I need?
I have the following PC Setup:
     AMD Phenom II X6 1045T Processor 2.70 GHz with 6 Cores
          with 2700 MHz Base, 3200 MHz Boost, and 4000 System Bus Speed, and 95 watts;
     HP Pavilion Elite, HPE-500y, 900 GB Free, new in 2011;
     Windows 7, 64 Bit;
     RAM 16 GB, DDR3;
     Graphics AMD Radeon HD 6450;
     Nikon, D200, with Raw Files;
     External Hard Drive for Original Photos, 600 GB Free;
     LR Catalog and Library are on Main Hard Drive;
     Monitor, Sony CPD-200ES, new in 2004.
I am thinking of buying a new monitor tonight mostly so I can do better photo work while enlarging the pictures to do it. I am concerned that while it will help my viewing, it will take more power away, and make my usage of LR5 even worse. Will a new monitor affect my performance? I am looking at HP Monitors with IPS. Is this the best recommended choice for LR and Photoshop CS6?
I think I would like to stay with a 6 core processor since I need to have several items open for other non-Photoshop functions. When running LR5, I had everything else closed. With LR3, I was able to have other things open.
I do not really want to buy a new computer and know that those I have talked with at this point are only guessing after looking for what they thought should fix it. 4 People from Lightroom Support have all thought I should not be having problems with my setup.
I bought one of the best computers 2 years ago. Is it really obsolete already so that I cannot use LR5? Is everyone else buying a new PC every 2 years? I used to go 5-7 years.
Even though I have figured out some of what my PC has, I really do not know technically what I am talking about so am at the mercy of other's help. Are there any solutions that might work short of buying a new computer?
I also have taken 40th anniversary photos for some people and am waiting to give them as a free gift since I am not a professional at all. I am hoping to get through this problem soon so that I can provide some nice memories for them.
I have not gotten any further than trying to adjust 1 picture. I have no comments on uploading speed, since I did that while still in LR3.
Thank you for your time and help.

I'm running LR with no speed issues on an Intel 17-860 quad core with about the same performance as your AMD Phenom II X6 1045T Processor. My system is also an HP, which originally had a single 1TB 7200 HDD. I've since added a second 2TB Black Caviar HDD, which provided no significant difference in LR's performance.
AMD processors do not implement hyper-threading and don't need it. I'd start debug by process of elimination:
1) Disconnect all externally attached USB, FireWire, or other externally connected devices except keyboard, mouse, and your single 1280 x1024 display. This includes all externally attached memory card readers, phones, ipads, etc.
2) Reboot and logon as Administrator.
3) Remove your Internet connection and turn off all Antivirus and firewall programs.
4) Open LR and under Catalog Settings set 'Standard Preview Size' to 1440 (slightly larger than your display width). Under the Metadata tab here make sure 'Automatically Write changes into XMP is NOT checked.
4) Create a 'New Catalog,' Create a new folder and add about 10 raw image file copies to it for testing, and Import it into the new catalog. In the Import module make sure under File Handling 'Render Previews' has 1:1 selected. Wait until all Preview building has completed in the Library module.
Try editing these image files inside the new catalog as you were previously.

Lightroom speed - very slow

I have a catalog that is very slow displaying previews. Often for several minutes it only shows a blank grey preview in the filmstrip and the main previews are very blotchy.
I currently have about 24,000 photos in the catalog. Is the number of photos the problem if so what is a practical limit?
My laptop is a dual core pentium with 2gb or ram.
Thanks,
Ed

Generally the previews are much slower than in the past in all views. However it is REALLY bad when it first starts. I should also mention that the files are stored on an external USB 2.0 drive.
Someone mentioned letting lightroom generate previews. I have a few questions about that. I thought most files have an embedded preview that lightroom should use by default. I normally import my camera raw files into lightroom and convert to DNG at import, sometimes I will shoot in jpg. The files that were working the slowest on the preview are .tiff but others do it as well just not as bad. Also seems like I read when lightroom generates previews they are only kept for 30 days after last accessed time. Is this all correct?
Thanks,
Ed

Lightroom 3 Very Slow

I am using Lightroom 3.4.1. It has recently slowed dramatically. I have a very large catalog - 361k images. The slowness comes in building previews.
and working in the Develop module. I am running an iMac 3.06 GHz Intel Core 2 Duo, 4 GB ram, 500gb of free space on the hard drive. I have gone through all the optimizing suggestions on the Adobe site. Is there a way to run a catalog this large efficiently? If I upgrade to a Mac Pro with more memory and faster processors would I see significantly greater speed in this large catalog? I built a test catalog and imported several hundred images and it worked very fast. Any suggestions would be much appreciated. Thank you! SDM

Hi Geoff
Well, I thought I was rendering standard previews, but it looks like my finger slipped, as I just checked and LR said it was rendering 1:1. I stopped and restarted the process.
But, for what is worth, I think the limiting factor for me is just getting the images off the disk. I have 1.6 TB of image data, and at a very optimistic 50 MB/sec of reading, it would take 8 hours just to read all the files. But, of course, I don't average 50 MB/s, and then LR has to process and write out the data, regardless of the size of the previews.
It would be interesting to compare a recent MacBook Pro with a Thunderbolt connector to a RAID to an older MacPro with a eSata connection.
Regarding my comment of running out of RAM--while I do think it is a problem in general, I just looked and it doesn't seem to be an issue right now. I am using about 8-10 GB of my 14 installed.
Cheers

Lightroom running very slow

I keep getting a spinning wheel when I use lighroom and it runs so slow. It is also taking up a lot of my memory. I have lighroom 5 ox 10.9.4. Please help

May be you can check to see if Spotlight is running in backgound on your system. Also, check that all your previous eclusions are still in place.
Ian,
Well as for Lion, my first plan of attack is to ghost an externally bootable drive and try things there first. :-) but I had another question... Perhaps I missed it somewhere, but is there a "performance tip" that involves excluding some LR items from Spotlight? I don't think I've seen that one.. What files are best to exclude? Thanks in advance.

Lightroom CC very slow in saving Photomerge dng

I am running a late 2009 27"iMac and never had any issues till the upgrade to LR CC. Now when every I run the Photomerge option for either HDR or panorama everything is fine till I try and "merge" and then it takes 30' for the process to complete and "save" the dng file. The same thing happens when using the Nik plugin's. When I use HDR Efex everything is fine till I hit "save" and then it takes 30-40' to save the file. While it is trying to save the image LR craws to a halt and it might take 5' to open a preview. Any help would be appreciated.

How big are the images?
How many images in the panorama?
How much RAM do you have in your computer?
What operating system are you using?

Lightroom 5.5 Import from Catalog *very* slow performance.

Importing from a second catalog from a shoot is *very* slow with the last version or couple of versions of Lightroom. It's been about 20 minutes and the import is moving glacially slow and is only about 20% done.
Here are as many stats as I have:
iMac 27" 3.5Ghz Core i7, 32G of ram, 3T fusion drive (the late 2013 model maxed out)
Master catalog has 117,000 images in it.
The catalog I'm importing has 948 images in it.
CPU use during the import is 100% used by lightroom (note that the multiple CPUs can go to more than 100% so this means I think that one CPU is maxed out, though LR can sometimes take 500% of my CPUs during an export)
Lightroom is using 4.2G of RAM (10G free in activity monitor)
Hard drive is fairly full, but still has 366G free on it (so about 10%)
Lightroom Mobile sync is enabled (not on this folder I don't think) but says "service unavailable" at this point.
Lightroom is fully up to date (5.5) on both iMac and laptop (also a mac in case that matters). Both are up to date with the latest OS software.
How I did it was:
Export the shoot as a new catalog on my iMac
Transfer it to my laptop (smart previews only, no masters)
Edit images, metadata, etc
Transfer the entire folder back (.lrcat, previews, smart previews) to iMac
In my master catalog do an import from catalog
Waited for ages for checking for dupes (which I can understand with such a big catalog)
Selected to import all, changing metadata and develop edits, and selecting to put new images in the folder (not sure why it asked as there weren't any new images)
The last time I did an import I started it and then went out somewhere so I didn't notice how long it took, but this seems completely crazy. In the time it's taken to write this up it's now about 20 minutes later and the progress bar is maybe at the 33% range. It's still working away, it's just crazy crazy slow.
Anything to help out or debug would be greatly appreciated. I suspect it's pure size of the catalog, but 120k isn't outside the realm of what I've heard people say works fine, or maybe the Fusion drive (maybe the OS is trying to move files around behind the scenes)?
Either way this didn't seem to be an issue until the last couple of versions (I haven't gone and re-installed 5.4 or 5.3 to check) and it's starting to really frustrate me

Hi Jim,
Great suggestion! It opens perfectly fine on its own. I even went as far as re-exporting it once it loaded but am still experiencing the same issue. That same catalog loads perfectly fine on my assistant's iMac.
I can't really think about anything that changed in my environment with the exception of a new Bootcamp partition to run windows on an external Thunderbolt HD but I doubt this is related.
I'm open to any suggestions while I am trying this again... 10 minutes of 'Checking for changed and duplicate photos'.

Very Slow preview rendering for lightroom 5 on import

I am seeing very very slow rendering of preview images only when using the import function in lightroom 5. By slow, I mean for a shoot of 60 shots in raw, it could take 30 minutes before I can preview them all in the pane to see which ones I want to actually import. This was not an issue with lightroom 4. It is not an issue when using lightroom. Previews are fast there, even for images I've never pulled up before.
My hardware is a PC, with an intell i7 chip, and 16 gig of memory. My nvidia graphics card has the latest drivers.
I've seen a few others reporting this issue, so I'm trying to log it as a bug. Even though the dial up support text on the adobe lightroom says available 24/7, it now plays a voice recording that says only available m-f.
Brad

I'm having the same problem using Windows 7 (64b). I just took a shoot over the weekend for a significant birthday event. Now I can't load the photos. The work-around doesn't work as the program freezes before I get the chance to select the camera under "files".
I recently upgraded from 3.6 to 5 as I was also noticing a slowdown in the import function. That turned out to be a bad move I think. I also deliberately cleaned up the CF card and removed all my video recordings, as this seems to be reported as part of the problem, but to no avail.
This seems to be a pretty major bug to have in a major release that's been around for a while now, that I'm expected to pay for, and no sign of a resolution to date!

recently bought a samsung NX30 camera which came with lightroom 5, after several hours of googling i got it setup properly with the correct camera raw to be able to access my raw images. I found my old laptop was very slow when processing the hundreds of images I usually take on a weekly basis. I bought a new faster laptop but when I looked for the cd with the software and serial I could not find it in the Xmas clutter. I downloaded a trial version of lightroom and got it working on my new laptop. Is there a way to access the serial number from my previously installed version and insert it into the trail version to make it work for me?
Myron

Mea culpa
While i registered all my cs2 thru 6 versions and my lightroom 2 thru 4 versions and recorded the serials and saved the adobe registration emails. Since this came as a freebee with the camera i neglected this vital step. I have the instslled version on my old laptop but want to install it on my new one. Thanks to Jim Hess I got the serial so all is well in my world and I will register it with ADOBE

Lightroom 3.3 speed, very very slow

Does anyone know why Lightroom 3.3 on a Mac is so slow?
The new version 3 was suppose to be faster than version 2. I purchased a new MacPro 12 core with 16GB of ram and with nothing else running, LR 3.3 is still as slow as it was in version 2.
I select multiple images make changes with sync metadata on, and it take minutes before changes show up. My activity monitor shows hardly any activity.
Anyone have any thoughts on why LR3 is still very slow?

rmherzog,
Actually, there are performance issues with multi-core machines (such as yours and mine) that are being researched at Adobe. Hard to pinpoint the problem so I suspect the answer will be a long time coming. Some functions seem to take advantage of all of my cores (like exporting) but other functions (like local editing and spot removal) are hit and miss. LR3 on the same machine is probably always going to be a bit slower than 2.x despite the advertising due to the change in algorithms; however, switching from a quad to a 12-core machine should ultimately over-compensate for that. I have a PC so it isn't limited to Mac machines.
I was able to increase performance quite a bit by turning off hyper-threading (that bios feature that makes the computer think it has twice the number of cores that it really has) and certain software that loaded with the monitor drivers. Now it thinks it has 8 cores instead of 16 and somehow uses those 8 more efficiently than the hypertheaded 16. In any case, depending on how Mac's work you might look into that. There are other suggestions in a similar thread relating to performance posted by Tom from Adobe that you might want to consider as well.
Jeff
PS - strangely enough, the slowest files on my machine are JPEG scans. Local editing can be quite burdonsome for me with these files whereas the RAW files seem to be only mildly sluggish but very consistent.

Lightroom 3.6 suddenly went very slow

Lightroom 3.6 suddenly went very slow to respond, after running reasonably fast for a few months.
Process Explorer shows that I have plenty of spare CPU and memory capacity.
I have no malware.

THe other day it went fast again for a while, but then reverted to being slow.

I am having the same problem running on a MacbookPro OSX 10.7.4 2.2 GHz processor and 16 gb memory. seems to have started this issue a week or so ago.

Very slow render on my beast of a machine

Hello, I have an issue whereby my rendering is very slow. I am using premier elements 12 with a windows 8.1 computer that has an 8-core amd 8350 processor, 8 gbs of ram, and I have an AMD 7970 6gb video card crossfired with an AMD 280x video card. Crossfire probably doesnt even work, but even with just the 280x, it should be faster than this.
I capture game footage, which is captured in xvid format, which I then import into PE12. I don't add any effects, other than some color tweaking, and some brightness/contrast tweaking. Then I export it in the same specifications it was captured in (1080p 30fps). A 7 minute video takes about 20 minutes to render/export using MP4 codec. If I try to use other codecs, it takes even longer. On my Mac Pro, using other programs like iMovie, this sake video would take like 2 minutes, and it only has a 4-core processor at a much slower clock speed, and only has a 6870 amd video card, which is like 1/4 the power. I feel that either the 8-cores aren't being used, or something else is wrong. No rendering that doesn't involve complicated effects should take longer to render than the footage length is. If the video is 10 minutes long, it should take 1 minute to render if it doesn't have chroma keying or anything heavy like that. How do I fix this?

Thanks for the tip. Bandicam already works when I choose "motion jpeg", and it works very nicely as far as being able to record in very high quality without disrupting my gaming performance. The issue is that it still takes longet to render a video than the length of the video itself. So a 6 minute clip, for example, will take about 15-20 minutes. This is unacceptable when ther are no major effects going on, such as chromakeying. I should be able to render atleast at speed play (ie, if a video is 2 minutes, it should take no more than 2 minutes), based on performance I get on my lesser Mac with a lesser CPU, lesser video card etc. It may be the rendering settings. I am using the stock "youtube widescreen HD" preset in PE12, and i manually change teh 720p to 1080p (like my footage). What else can I try?
The only thing I can think of is that PE12 doesnt use 8 cpu cores, or it doesnt use OpenCL. Does it? I cannot find any settings in PE12 for "enable multicore processing" or "enable openCL" etc.

Lightroom 4.4 very slow - tried everything

Hi all...
Lightroom 4.4 is very slow for me... everything takes longer than it should and it's driving me nuts. Can anyone help?
Some details:
I have LR 4.4 on a Macbook Air. I have two libraries:
Internal - 5,000 photos
External Drive - 21,000 photos
My external drive is not connected and I am working with photos on the internal drive... so it's only 5k photos.
I've already tried all of the troubleshooting tips:
Purged camera raw cache
Increased camera raw cache to 3GB
Purged video cache (even though I have no video files in LR)
Deleted all previews (8GB worth)
Optimized catalog
Restarted LR
My Macbook Air has 30GB of memory free.
Any suggestions? It's driving me nuts.
Thanks!

I can now report from both sides of the fence. Up until yesterday, I had a four-year old Core2Duo system, 8GB, that had the dreaded slowness. Not as bad as described above perhaps, but there was clearly something not working as it should. Using matrix-based monitor profiles and updating video card drivers relieved some of the symptoms, but the disease was still there.
At the same time I used an i5 16GB system that was much better. Not good (as in instantaneous), but acceptable.
This morning I fired up my new system for the first time and sent it on its maiden voyage. Naturally the first thing I did was open Lightroom 4.3, and...yes. So that's how it's supposed to work! Snappy, immediately responsive, switching images like nothing ever happened.
Phew.
Now this is a pretty high-spec'ed machine, i7-3820, Asus P9X79 pro, 32GB, SSD. Let's not hope these are the real requirements for good Lightroom performance. But I did reuse the old video card, an ATI 6670 running the 12.8 driver, and it works just fine.
At the moment it's a pretty lean setup: Aside from mobo and video drivers I've only installed Lightroom, CS 5.5 Design Premium and Eizo calibration software. Anti-virus, mouse and keyboard drivers, file synchronization software, font manager and Office remain. I'll keep a close look at how Lightroom behaves as these are added.
Bottom line, and there's no doubt about it: Brilliant as it is, there is sickness in the Lightroom code somewhere. For some people, the unlucky ones, the symptoms are bad. Most people get away with a mild flu, and some are immune.
