I thint this is an easy solution for the 2 second delay that can bee seen on every machine.

ОК. Just checked it. Re-imported files as DNG files with 1:1 Preview.

Example of lack whenever using the Spot removal (heal) for more than, let's say 3 times, the next is SLOW. Better don't ask about fixing times on eyes sharpening and/or skin under the eyes with the adjustment  brush. Noticeable lag even on RAWs from Canon 40D which is with 10 Megapixels.

Guys, you gotta be kiddin' me! Do I need to explain that I now work with 50 megapixels and what that means to me?

My rig is: i-7-6700K @ 4 GHz, 32 GB RAM @ 2400 MHz - OS and scratch disk on EVO Pro 840 500 GB SSD + Black Caviar 1 TB for catalog and actual images. GTX 970. Win 10x64 bit. Current catalog set on 3 GB Video, 88 GB RAW cache.

PS: I have tested on the SSD no change. Constant utilization of CPU from LR whenever calculating a local adjustment or similar (observing it on Process Explorer).

What excuse do you have NOW???? Please let me know. 

Jeffrey Tranberry, I am complaining about this and also about the lack of custom shortcut keys feature for quite some time already. Considering migration to Capture One. Currently in workflow adoption and testing phase.

Eric Chan, My issue is not with the your department, I guess. Whoever works on the local adjustments should improve performance-wise dramatically!

IMO and according to my experience it's solely CPU.

Does that mean that if work with DNG files (converted from CR2) this would   improve the visualization of images and ergo their edit (especially a heavy local adjustment speed)? Challenge accepted. Will come back with a verdict.

Bobobo168, Video as weird as it sound as 5 times faster with adobe. Images are another story.

Even if you don't do it for format loading, Sony had some great success with image (really video) processing using OpenCL http://on-demand.gputechconf.com/gtc/... 🙂

I just purchased a powerful laptop with hopes of taking advantage of the dedicated GTX 860m GPU white using Lightroom 5 instead of the Intel CPU graphics. The laptop uses Nvidia Optimus technology and I have a feeling that Lightroom 5 isn't an application profile that is supported yet. Photoshop does appear to be supported in this situation though.
Does anyone have insight into this issue? Below are the steps I've taken in Windows 8.1.

-Open Nvidia Control Panel
-Select Manage 3D Settings
-Select Program Settings tab
-In 1st Drop down field, Adobe Lightroom is not available (Adobe Photoshop is)
-Clicked 'Add', selected lightroom.exe.
-Switched 2nd drop-down field to "high-performance Nvidia Processor"
-Clicked apply
-Opened Lightroom 5 and the Dedicated GPU did not turn on.

I applied these same steps for Adobe Photoshop and everything worked fine.

I spoke with an adobe tech support rep and he mentioned that Lightroom hasn't implemented support for this yet? Why would photoshop be supported and not Lightroom?

Windows 8.1
Intel i7-4720 cpu
Nvidia GTX 860m 4GB gpu
8GB DDR3 memory

I completely hear you about the need for multiple import sessions. As we speak/type I'm importing ~2000 images and waiting to start another session of another 2000+ images. If I could just start them both it would be a huge time saver for me. As it is I need to stick around at the studio another 35 minutes so I can start the second session and then head home.

A know a lot of people that would like to be able to start one session with one set of parameters (file renaming, keywords, etc) on a group of images, and then immediately start a second import session on a second group of images.

Your card reader could be a bottleneck, but either way multiple import sessions (from several card readers if necessary) could help!

Actually there are some simple improvements which could implemented very easily. For example the import of photos does not use all available resources.

Importing e.g. 1200 RAW images, converting them into DNG on a Mac Pro with 6 Cores, 3.5 GHz and 32 GB RAM, from a SD Card into a RAID Array ... you would simple expect a quite quick progress.

But Lightroom is slow. It doesn't make use of the RAM, it also doesn't make use of the CPU power. It seems it processes each image in a sequence, instead of processing 8-16 Images in parallel. It's frustrating to see that there is no actual bottleneck, just Lightroom which does process the images sequentially. It could also start generating the previews after the import, but no... the preview generation starts _after_ the import of all images.

- A big issue on import. While import you can not work on Lightroom, so this slowness blocks actually your workflow.
- Another big issue on export. It takes so much time to export e.g. 100 images. At least here it doesn't block your workflow.

If at least Lightroom would process multiple images in parallel, it would compensate for the lack of multithreading in the processing itself.

HoHoHo !!! So !!! It is very hard ... HaHaHa. Learn from this company.
It seems that Adobe is struggling !!!
