Best Lightroom Performance Options?

I thought that LR CC didn't wait to get new stuff. Isn't that one of the selling points for CC over the standalone LR?

Just wondering. If you have your photos on a disconnected hd and are using Smart Previews and have selected the option to write changes to an XMP file what happens if you edit using the Smart Preview? Does it wait until the hd with the photos is re-connected to write the XMP? Does it never write the XMP? Does it write it some other place?

This question seems like it would be better off in it's own thread, it has nothing to do with the existing thread.

Calling changes to the program "stuff" obscures important concepts, such as "features" and "program architecture".

CC does get new features when they are available, and these have been announced by Adobe. There has been no such announcement about additional uses of the GPU, which means they are still working them and any such additional uses of the GPU are not available at this time. In any event, changing what the GPU does is a major change to the underlying program architecture (as opposed to adding a new feature to the program), and I'm fairly certain that major changes to the program architecture will only be made in between major upgrades.

Mainly using brushes to touch up images, and moving from one image file to the next. Sometimes it takes a good second or two to load the next image. I know its way quicker to move between images in the library, but obviously its necessary sometimes to have to move between images in the develop module

THis is most likely the cause of your problems. Brushing on a 4K monitor will be slow. It might speed up if you turn off the GPU acceleration, but then other operations will slow down. My OPINION: right now there isn't a good solution for brushing on a 4K monitor, it will be slow if the GPU acceleration is on, and other actions will be slow if the GPU acceleration is off.

Im thinking it may be best then, to keep my main catalog on the iMac internal drive.

This is not the cause of your problems.

Thanks Paige. What do you think the huge lag is being caused by as far as switching between image files in the develop module (filmstrip)? I even notice some lag when moving through images in filmstrip in the library, just not nearly as bad. It was nonexistent when developing files from the Sony A7ii. Almost makes me wish I never upgraded cameras.

PS, thanks for your help!

No, the develop module always creates fresh previews every single time, it doesn't use the previews on the SSD. And regardless, SSD and 1:1 previews don't affect EDITING speed.

What I've read is that the preview is loaded first into Develop, and if a 1:1 preview does not already exist, it is created. There is also another cache involved, from what I've read.

While this won't help the OP's problem with brushes, it should help speed up moving from image to image in the Develop module.

Smart Previews for Faster Performance

You’ve always been able to use Smart Previews in the Develop Module as a way to edit photos without having access to the original images on disk. Astute customers reported faster performance in the Develop Module when using Smart Previews and keeping their original images disconnected from their computer. Now, you can set a Preference in the Performance tab so that Lightroom will always use Smart Previews in the Develop Module, if they are available, even when the original files are also available.

To do so,
  1. Choose Edit > Preferences.
  2. In the Preferences dialog, select the Performance tab.
  3. In the Develop section, select Use Smart Previews Instead Of Originals For Image Editing.
  4. Click OK and then restart Lightroom.

Also change your 1:1 preview size and preview quality to medium or low.

Hope this helps.

I will check this out for sure.

Thanks

Sure, but what you are missing is that different previews are used in Library and Develop. This has been referenced many times in the specialist lightroomforums.net, for example from the gentleman who posts here as Johan Photo

Like Victoria already mentioned, the previews in the Library module (and all other modules except Develop) are AdobeRGB. The previews in the Develop module are Lightroom's internal color space, which is much bigger. If your monitor has a bigger color space than AdobeRGB, you may indeed see that difference.

Lightroom always generates a new preview in the "Melissa" colour space when you access the image in Develop.

I guess you mean what Adobe is missing, since I only quoted their Lightroom performance notes.

Also, read the referenced article, it says the same.

Minimal: These previews are the small, low-resolution JPEG previews embedded in the photos, which the camera generates. They are the fastest type of preview to create. The Filmstrip and Grid view of the Library module uses minimal previews temporarily, until Lightroom renders standard-size previews for those thumbnails.

Embedded & Sidecar: These previews are larger, also camera-generated, and they take a little longer to create than minimal previews.

Standard: Lightroom creates standard previews. They use the Camera Raw engine for processing. So, the sometimes appear different from minimal or embedded previews,

However it appears to be stating that if you have 1:1 previews (which are different from the ones used for other purposes), they do not have to be regenerated for use by Develop.
