Experiencing performance related issues in Lightroom 4.x

add me to the list for what its worth...Has Adobe issues any sort of formal response yet?  I can't see one...I've loath to run the process that some have suggested here because my cat is HUGE  (10k+RAW)  would take all nite to re-create previews...

re-draw is so slow I can see the pixels being created....same catalog as LR3....Also added 400 new RAWs yesterday to the LR4 catalog and still no effect.  Running Mac OS 10.6.8, Mac Pro, 12GB RAM.... Opening LR3 works without a hitch...  Can Adobe please respond formally....This product is not usable!!

Same issue here with sluggish sliders in LR4. LR3 was and still is much faster.

I'm using new lightroom on two computers. On both it is very slow. On both there was no performance problem with LR 3.6.

On one of my cmputers I have imported just around 40 JPEG-s to test new lightroom and it is a horror. Sloooow with just 40 JPEG-s?

Also removing ajustment sliders for chromatic abberation is a mistake in my opinion. Sometimes i have to work with files stripped from data and now there is no tool to correct it. I dont want to say that new automatic feature is bad but it is bad that adobe have removed manual sliders.

I know it is not the topic here. What really makes me sad is that if you want to use couple of new cool things that came with lr4

you have to deal with things like slowlyness and usable stuff like chromatic abberation sliders being remowed.

Lightroom 4 is VERY slow for me, but I wish it was "only" that... I also find the way he converts the image to the new version, really horrible.

In the new engine, all my images look greyish.

Here's a sample (crops), first the original (Lightroom 3 "2010" engine), then the new version (Lightroom 4 "2012" engine):

I simply can not accept this detriment in image quality.

I am also experiencing downspeed using Lightroom 4.0 when switching from one module to another several times, and tremendous downspeed when using the local brush adjustment and observed that my Random Access Memory usage is reaching 98%.

Hoping that Adobe Lightroom Team will fix this issue like what they did in Adobe Photoshop CS6, I watched the sneak peek featuring the Liquify Filter in Adobe Photoshop CS6 and it seems like a charm.

Overall, Lightroom 4.0 is a great application for digital photographers.

Shame that some people are having issues. Upgrades should be seamless IMO, and the kind of performance issues mentioned here would drive me insane.

Lucky for me I guess LR4 is blazing fast - better across the board than LR3, especially in bulk handling of metadata and develop adjustments (WIn7-64 tower, i7 2600k 3.4ghz, 16gb ram, 4.5tb, migrated LR3 cat of 50k images).

Adobe has a good guide to speeding performance here, but you really shouldn't have to change anything to accomodate the upgrade, and the kind of outrageous slowness people are describing here - waiting five seconds for things that should definitely be instantaneous - can only be bugs it seems. Either that or there is (for some user segment) a best practices routine required for LR4 that is different than LR3, and Adobe hasn't informed everyone.

Seems like a lot of people talking about higher memory usage, and a lot of people with problems posting saying that they have 6gb of ram. I wonder if people aren't just swapping. 6gb is perhaps not enough for guaranteed swap-free performance, especially if you're multi-tasking with other applications and if you have some system bloat in general. RAM is so cheap it's certainly an easy fix.

Also I wonder if people are doing things such that their camera raw cache has to be rebuilt, and they are misinterpreting the cache re-do as general slowness in the Develop module. As far as sliders, all slider operations should always be smooth and instantaneous I think, even on slower machines, and definitely on faster machines.

I just wanted to include my experience of LR4 in this forum.

I too have upgraded from LR3.6 and initially I came to this forum after experiencing performance issues that would have, in my opinion, made LR4 unusable.

I removed LR4 Beta  - as a matter of good practice - before loading the release version of LR4. I installed LR4 alongside LR3.6 (i.e did not remove 3.6 before 4).

I opened LR4 and pointed it at my "old" LR3.6 Catalogue and was promted to convert the catalogue for use in LR4.

I ran through the automated process and thought nothing of it. I converted all my photos to PV2012

Note: LR4 created a COPY op my LR3.6 CAT that sat alongside the old one.

400 images in my catalogue, some tiff, some NEF, some JPEG, some DNG!

I then noticed the performance issues, especially with flicking between images in the film strip ( ~3 second delay between redraw). I also noticed this with WB, Exposure and a number of other sliders lagging typically 1-2 seconds behind.

Note: I did not notice slow performance or other performance issues within the Beta (created a fresh catalogue anyway)

# My Resolution:

- Removed 3.6CAT (backed up to another folder of course)

- Renamed the LR4 CAT and Deleted .irdata folder and previews folder.

- Loaded LR4 and pointed it to the catalogue, waited for LR to create the default folders. (1-2 minutes, it did not take long)

- Rendered all previews in catalogue:  library>render previews and render 1:1 previews

- Ran optimize catalogue (as a peace of mind option)

LR4 not runs as well as 3.6, which, is all I could ask for.

If anything is not clear of you want to know more if i left anything out, let me know.

For what it is worth I have included my PC spec:
AMD Phenom, 3.7Ghz, 4GB RAM, ATI4850, WD Black 640GB.

LR4 is, IMO, a little more RAM hungry than 3.x

Message was edited by: Screenynamettr That should say LR4 NOW runs as well as 3.6

I had intermittent slowness in LR3. ranging from unusable to highly annoying. Other times it ran smoothly.    the only thing I could puin down the slownewss was disc activity. As soon as the HDD LED was either constantly on or flashing rapidly, LR3 slowed down to a crawl and slider repsonsiveness was terrible.. like 5 seconds before a change happened.

LR4 has upto now been fairlry responsive

I have an i7 930 with 6Gb of RAM overclocked to 3.8Ghz

Adobe should look to the disc drive handling IMHO

2.7GHz i7 / 6GB (Lenovo G770)

MS Win Home Premium 64-bit

LR4 64-bit

Extremely slow ... click an image to enlarge and I can almost watch the screen redrawing. Touch any slider, but perhaps especially denoise, and the fan comes on full blast and the whole machine slows; Export 6 2048*1536 jpegs - takes 20 seconds and CPUs at 100% much of the time; single click on a filmstrip image - 80-90% CPU; animated activity icon is whirring for almost any activity I care to try.

Catalogue is < 3K images at the moment. I always build 1:1s on import; the slowness is the same whether I edit newly imported images or images which were already in the catalogue from LR 3.6

LR3.6 was fine on  the same machine.with the same catalogue.

I have to say I didn;t notice this level of poor performance  with the beta, but then I didn't try to import all my old images either ...

I'm experiencing a similar issue.  Lightroom 3 is very fast.  Lightroom 4 is unbearably slow.  Even applying a rating to a photo takes a couple of seconds.  It took me forever to process images from a volleyball match last night.  Moving from the Develop Module back to the Library Module takes a few seconds.  Previews take forever to render.

I originally did my processing using Capture NX2.  I switched to Lightroom 3 a few months ago--and was amazed how much faster it was!  Now, Lightroom 4 is slower than NX2!  I would go back to Lightroom 3, but going back and forth between Lightroom 3 and 4 makes managing the catalogues quite complex.

I recently purchased a new ThinkPad computer.  I'm using Windows 7 (64 bits).  The computer has an Intel Core i7 Processor and 8 GB of RAM.  It works great with Lightroom3, but is unacceptable with Lightroom 4.  I hope that Adobe introduces a fix very soon.
