Lightroom CC: Performance is sluggish on a brand new MacBook Pro

I recently purchased a brand new MacBook Pro 2018 13" and I was hoping to find Lightroom CC to be a bit more performant. But it's sluggish. Scrolling photos and general operation is just not as fast as you'd imagine it to be on a brand new computer. Other apps are speedy and feel fine so it has to be Adobe's codebase for the reason why. Lightroom CC should be fast seeing that it was rebuilt from the ground up. Please, please, please spend some time ensuring its fast and responsive. Don't keep piling on features and make it more bloated. Speed and performance are so high on the list. Please Adobe, don't make the same mistakes as your other software.

I agree James. I am working on an almost new MacBook Pro and the performance is an issue I think.

Have to second these motions.  Running LR Classic CC on a eight-core 3.0GHZ MacPro with 4TB SSD, 128GB RAM, and twin 6GB GPUs.

Frankly, LR 6 ran faster on my MacBook Pro!

Takes over an hour to optimize the catalog.  Been importing 8k images this morning (50/50 raw and jpg) with standard previews and it's been going on for three hours.  Part of the issue seems to be LR 7.5 insistence on performing import in parallel with building previews.

All other chores are sluggish as well.  And if LR 7.5 is left running, doing nothing but sitting at idle, it will gobble up 75GB of RAM!

It's a pig.

James, for a point of comparison, can you give us an idea of what you upgraded from? And particularly what resolution monitor you were using on your previous computer?

Hey there Victoria! I upgraded from a MacBook Pro 15" 2015 model. With my new computer, to get any reasonable performance, even when just scrolling the photos, I have to make the thumbnails as big as they can be and I lower my screen resolution down to 1280x800. Not only that though but even editing a photo or two, my whole computer whirls up the fans and it gets incredibly hot to touch. I mean, it's crazy really. No other app does this on this machine. The only time I ever hear the fans is when I'm editing a photo in the new Lightroom CC.

Hi there, same here! I upgraded from a mbp retina mid 2012 i7, 16gb internal memory with 512 ssd, to a mbp 2018 i7 2,6 GHz 16gb 512 ssd. For instance viewing photo’s fullscreen via shortcuts F is slower on new MBP. Takes sometimes seconds to go to the next photo...my 6 Year old does it better...help would be appreciated, obviously...greetings from Holland, Joan in both cases (without) same monitor, eizo cx240.

I've seen an open bug on slow full screen that's specific to Mojave. Lightroom Classic CC: Slow preview in full screen (F)

For the rest, which module are you using when it takes a long time to move to the next photo? And previews pre-rendered?

Also did you set this machine up fresh, or transfer data from Time Machine? I'm seeing some performance reports from Mojave upgrades that disappeared when doing a clean install of the OS.
