Anyone else notice that lightroom 4 is slow? Ligtroom 3 always ran fast on my system but Lightroom 4 seemlingly lags quite a bit.

My system is:

2.10 ghz Intel Core i3 Sandy Bridge

8 GB Ram

640 GB Hard Drive

Windows 7 Home Premium 64 Bit

It's now impossible to see the wood for the trees in this whopping 43-page long thread.  Many of the original 4.0-4.2 performance issues have since been resolved, and it's impossible to figure out who is still having problems, and what they can try.

I've started a nice clean thread to continue this discussion for 4.3 and later. http://forums.adobe.com/thread/1117506  Thanks to Bob_Peters for the suggestion.  I'm locking this one, otherwise it'll continue to get increasingly unweidly, but please feel free to continue existing discussions on the new thread.

I have a much faster (and newer) system, with twice the amount of RAM. I'll test tonight and see if I notice any slow-downs, but, like with all software updates, it may well be that LR 4 now demands more of a system, and your PC may just be on the borderline of acceptable resources for optimum performance?

On my i7 Quad Core, 16Gb DDR3 RAM, 2Tb SATA II Hard Drive PC, Lr 4.1 is noticeably slower than Lr 3.x. For large jobs (processing high quantities of photos) I am now using DxO Optics Pro which processes very quickly. On Lr 4.1 I would have lost many clients at the speed that Lr 4.1 processes.

DAVE - DXO is indeed VERY fast but the browser and its inability to cache and display changes makes the program overall slower for me. How are you dealing with that aspect of it?

Just a side note - I have changed the setting to recieve emails a few times - as long as adobes doesnt record those settings and keeps sending me emails I will keep speacking my mind

The release version is as slow as the beta version. I am testing both on my Mac Pro 3GHz 8 Core, 16G Ram, hard disk is Raid0 x 3.

The response is unaccpetable.

Its possible that it has to build new previews and Camera Raw cache.

It seems like I mostly have lag when switching to full screen or going into the develope module. It also seems though that this is only for the first few mins I have it open. If I go to the develope module it will be slow the first time and fast the rest of the time. Hopefully they will fix this. The new develop and video features are too good to go back to Lightroom 3.

Yes, same conditions for LR3 and LR4 : LR3 was fast, LR4 is very slow. A trick indicated by a user, make LR4 working better but after a certain time, rebooting or so, LR4 is becoming slower. So much posts concerning speed (actually very low speed) couldn't be only the fact of users configurations. My LR3 library is 30 more bigger than the one of LR4, configurations are the same concerning previews aso.. Even DxO which was not the fastest RAW software in the past, is now faster as LR4 !

Curious thing that even LR3 was a little bit slower from time I installed LR4 beta, replaced now with released LR4.

I think I will not upgrade to LR4 until I've retrieved speed of LR3, particularly because from my personal point of vue, LR4 is NOT a major release.

One of the things that both LR3 and LR4 share is the acr cache, which stores the part-rendered .dat files (for raw files) to speed up going to 1:1 views. I've always been suspicious as to how well they do this sharing, and I would suggest deleting the acr cache (Preferences/filehandling/purge cache) and letting LR4 build a new one without LR3 interfering with it. See if that helps.

Bob, thanks for your advice, I will try this and see what happen. Another thing I'm trying is to install LR4 alone on another system, with no LR installation at all, to avoid some shared files with LR3 ? This should give the right information if no improvment, where to look : propably graphic driver.

I'm agreeing with Armin-H.  LR4 is running incredibly SLOW, not like LR3 for speed at all.  Just making brush or cloning adjustments causes a 3-5 second lag for them to take effect.  Not acceptable for Adobe products.  I'm running  Mac Pro QuadCore Xeon w/ 11GB or RAM.  That should be sufficient to tame just about any beast of a program.  The lag occurs even without any other programs running.  Why should that be?

They need to clean up the code....it's just sloppy coding. There should be no reason that LR4 causes this kind of havoc on such large machines.

Compared to LR3 I do feel it's a lot less responsive.

Moving sliders like clarity produces so much lack that it's kind of impossible to get a feel for subtle changes.

I'm on OS 10.7.3 on a 8-core 3GHz Mac Pro with 24GB RAM, so I don't think performance is due to a lack of system resources.

I like LR3 for the immediate response of controls. That feeling is gone with LR4.

The development algorithm is clearly different from LR3. It brings out a lot more levels in deep shadows.

It's hard for me to say if that's a good thing, yet, but the fact that everything is so sluggish makes it hard to have fun testing the impact.

When I look at the CPU load on the activity meter, something as simple as changing the black level in LR4 produces a massive spike of activity on all cores. A similar manipulation in LR3 is hardly noticable. No wonder the sliders don't really follow small changes.

Hi Folks!

I allready wrote in the beta time in the therad about that lr4 beta was sluggish. I wrote this:

I Installed LR4 Beta today on 3 Machines. I worked on 5DMKII raw files. dng and cr2 files.

Here are the hardware settings:

1: I7 930 overclocked to 3.8ghz , 128gb ssd as boot disk, 3 raid 0 disks (6 x 1.5TB) for datas and as scratch disk for cash and so one, 12gb ram, nvidia gtx570, win7 x64 ultimate

2: same as nr one, just a quadro 4000 as grapics card.

3: mac pro with 2 intel xeon 6 core prozessors, 12gb ram and ati hd 5870, osx 10.7.2 lion

Conclusion. When working in Process 2010, everything works realtime, fluid, perfekt. switching to process 2012 it is simply AWFUL. moving a slider and 1/2 - to 1 second untill i can see the results in the pictures. it gets realy bad, when i turn on the sharpness and the lens correction. it is simply not possible to work on this piece of software. completely useless at this stage.

These are pretty high end machines with a lot of power. i know lr4 is BETA, but the performance must grow about 800%, or lr4 will be useless for a smooth workflow.

I just red, that a person called COW answered in this thread that lr4 is fine now and fast! i tried to reply in that thread, but now that thread is set to READ only for me, so i have to write here.

i installed the software on all these 3 machines today. i imported the catalogue and ...bam. sluggish like HELL. unbelievable. 7D files and 550D files are a little bit faster but hell it is still sloooowwww.

i did the trick like lee told me in the other thread and i tried to import fresh and clean cr2 files driectly to the 2012 process. like in the beta it became a liiitttlleee bit more fluid. but just a little bit. so i decided to clean my complete preview database and my cache and let it completele rebuilt. i did that on my mac pro dualprozessor machine which runs on 10.7.3 lion. lr4 is installed on a samsung 500mb/sec ssd and the pure cache disk is another ssd wird 128gb. just for cache and preview database and catalogue. i think this is quite as fast as it can be.

so i completely renewed everything and.....again. a little bit faster but agins much to slow.

when you have the lens correction turned off and sharpness turned off, it is likely useable. when you turn on a second monitor it beginns to get slower. when you add lens correction and detail/sharpness........bam. slow as hell. i recognized the cpu usage and saw that the usage was unter 8% on all 12 cores. no cpu usage and unbelievable slow??? working in lr3 is completely flawless. not one stuttering or anything. i am completely not satisfied with this piece of software - sorry!

i heard a trick from a friend of mine who told me, that not the cpu power is important. lr4 uses the ram and the faster the ram is, the faster is lr4. so we built in a new ram from 12gb up to 24gb. the old ram had 1330mhz and the new one had 1800mhz. the speed raised up but it is STILL not completele fluid. when i did some adjustments to a picture, the sliders become unbelievable slow, as more and more you move them. on all my machines.

adobe, i really like lr and i grew up with this product. i allready even bought the upgrade. but no...this is not a piece oft software that can be used for a fluid und fast workflow. it can be used for single pictures to create really good results....yes, but not for a fast and fluid workflow what lightroom once stood for.

Sorry to say that but you have not completed the mission. it was a failure. having lr4 and a user who prefers lr3.6 should not be the goal!

Resolve these problems please as fast as you can guys!

King regards Frank!

I just upgraded and found the same.  I am running a Dell i7 w/ 12 gigs ram, NVidia 2 gig card with llatest driver.

The develop module is where I noticd it.  with the 2010 process, seemed fine, but when the conversion was made, moving some of the sliders took approx a second for the slider to move and image to update.  Hope Adobe figures it out.  Will be using LR3 on any big jobs for now.

Hi Frank! I just read up on your post from 7 months ago. Have you figured out a solution. I'm in the same boat. When you have a moment please let me know what you think? http://forums.adobe.com/thread/1057108

I have no faith in Adobe stepping in to admit their poorly sluggish piece of software!

Thanks,

Lam
