Lightroom slow on Mac Studio (Again... But I can't understand)

Yes, i have sam problem, it's pain to work with LRC on Mac Studio m1 MAX 32gb. I need to edit large wedings, and it's not normal to work sow slow. I tried to build difrend size priviews but in develop modele every pciture load from 2-10 sec 😞 Sony a7iv RAW (not compresetd)

Thank you all for your answers!
So, I think there is also a psychological parameter ':) I must admit that I have a hard time accepting having performance issues with this type of machine, everything is fast and snappy so as soon as an application does not respond as quickly , I find that problematic.
In front of a client, a machine that has trouble navigating between images, it's not great 🙂
Anyway.

I think the previews were good but I redid them anyway, in Auto (= 5120px).

• Library module: it's ok 🙂
• Library module - Full screen: Not satisfactory. There is a (fairly short) delay between the key and the display, which is very frustrating. For me it's already too much in front of a client 🙂
• Development module: when navigating slowly there is a (rather short) delay, when navigating quickly there is also a sort of flash when the image is displayed. I'm also disturbed by the filmstrip which doesn't refresh instantly (it's instantaneous in the library module)
• Development module - Full screen: that's the worst! It's between half a second and a second between the click and the display. Unusable, even for me.

Perhaps the best alternative to full screen is to stay in loupe mode without any panels (shift + TAB). I don't understand that the difference with full screen is so important, the image size is almost the same, minus the additional information... Maybe there is a big optimisation issue here.

Please Adobe, don't rest on your laurels 🙂

Thank you,
Matt

Your lightroom Classic version is behind. Current version is 11.5 so I would first make sure to update. Second is to describe what is exactly slow. Are you browsing images in Develop? That will always take a second. If you are browsing in Library, delays can be caused by the previews not being large enough as already mentioned. You just need to make sure your standard previews are large enough for the resolution of your screen. This is set in catalog settings> File Handling. Make sure it says auto for standard preview size.

By far the fastest way to browse through images right after importing is to use embedded previews created by the camera. This is done by selecting embedded in the import screen. Those are 1:1 by default. ou will get slight shifts in appearance if you take those images into Develop because Adobe's raw converter works differently than the camera one but it is one way to speed up the process massively.

(These are my responses to the questions you asked me in the other thread that was actually about PC hardware.)

Are you seeing the same slow performance in all areas of the applications, or does it vary? Because it probably does vary, and below is what I have consistently see, in rough order of fastest to slowest:

• Library module, image preview built: This is lightning fast for me. If I hold down the arrow key, every image with an existing preview flies by quickly at a very high frame rate. For example, it is practical to preview a time lapse sequence smoothly by holding down the right arrow key. 
• Library module, image preview is not yet built: There can be a delay displaying an image while Lightroom Classic generates a preview. It may take more time if there are many masked adjustments, and it may take even more time if the Preview Cache settings in Catalog Settings are set to higher pixel dimesions and quality. But it has gotten fast enough that I don’t think the wait is a problem. 
• Develop module, image in Camera Raw cache: The Develop module display of an image is higher quality than the Library preview, so this takes longer than the above two. But for me it does not usually take almost one second per image, and in recent versions has become quite fast. 
• Full screen: Not as fast as Library module Loupe view, even when preview is built. There are noticeable delays. My understanding is that Full Screen has not received the optimizations of other views, and my also that when using Full Screen in the Develop module does not take advantage of the GPU acceleration in the Develop module. (I could be wrong on that)
• Develop module, image not yet in Camera Raw cache: This will usually take the most time to appear, because Lightroom Classic has to build the RGB version of a raw file at higher quality than the Library module. For me it might take up to one second, depending on the extent of adjustments. It could take several seconds on an older computer with a weaker GPU, but a Mac Studio should not have a problem in this area. 

So are you saying it can take up to one second in all five scenarios, or only in the last two? What I would expect is that the most significant delays are Develop module viewing uncached images, and Full Screen viewing because Adobe has not optimized it fully.

Just a note about my system, my M1 Pro MacBook Pro is often closed and docked to two desktop displays, but they are relatively low resolution (2560 x 1440 px and 1680 x 1050 px). I would expect images to display somewhat slower on a 4K+ display in the Develop module.

To make sure previews are present in folders/collections I am viewing, I enabled the Generate Previews in Parallel settings in Performance tab of Lightroom Classic Preferences. That should be enabled on a Mac Studio because it has enough cores to handle it.

The worst case scenario might be Develop module, not yet cached, on a 4K+ display. But the other view scenarios should be much faster.

In LrC, please go to Help->System Info and show us a screen capture of the first screen. Use the Insert Photos icon to include your screen capture in your reply. DO NOT ATTACH FILES. DO NOT COPY AND PASTE more than the first screen.

Also please tell us the size (in pixels or megapixels) of your camera's raw images. Do not tell us megabytes.
