Pretty much every single thing I do is soooo slooow, it's too painful at this point. I can't level my pics, hard to crop, use the brush tool, post to Flickr, you name it. You either have to fix it, or lose me. I've spent alot of money on lightroom and photoshop and up until now, I've lived with the issues I've had because for the most part, they were minor. This is major. Please pay attention and please help us!

Why are there zero replies on this after 10 months? I suppose the original poster is not too happy with the performance of this forum? I have a MacBook Pro it’s four years old. I have been using aperture for editing photos for 5 to 7 years. Apple doesn’t support it anymore so I migrated to light room cc. It’s maddeningly slow. Aperture is better. Do I really have to go buy a new freaking computer?

Hi Martin,

A new computer probably won't do you any good, unless you can borrow Deep Blue from IBM.  I migrated to LR Classic CC last week and it is many times slower than LR 6.  I am running a Mac Pro with an eight-core, 3.0GHz CPU, a 4TB SSD, 128 GB RAM, and twin 6GB GPU.  This is a $8.5k machine!  Even without the after-market upgrades, one can't do much better than that in the Mac world.

My images are on thunderbolt-connected 20TB G-Tech drives, with amazing throughput.

Importing is the slowest process, perhaps because LR 7.5 performs importing AND preview building in parallel.  Not sure if possible to disable that, but it seems to be a dumb idea to implement without Adobe supporting symmetric multiprocessing.

Yes, I have a large catalog, over 20GB with 3.4 million images; however, when I upgraded my hardware from a MacBook Pro to this MacPro back in the good old LR 6 days, I saw a tremendous performance improvement—which is logical given the hardware differences.

Those improvement all went away last week under LR 7.5.  Yet my catalog was over 34GB in that old LR 6 version.

Seems the only promise Adobe fulfilled was a reduction in the catalog size.

Wait, they never claimed that; it was observers whom migrated who mentioned it.

LR &.5 is also an incredible memory hog.  Sitting idle after an import, it will gobble up 75GB of RAM.

Seriously?  Yes, really.

OMG. I have assumed so far that I have no other options - I used Apple Aperture for several years and am pretty expert... ramping up on LR now that Apple no longer supports Aperture. Currently I am using both apps for busy work flow to keep things moving ... semi - pro work and no Photoshop training. Thanks for sharing your experience. Doesn’t strike me as a sustainable state of software development for Adobe.

There are other options out there, like Capture One and ON1.  The problem in migrating to another platform for me is the vast number of presets and Smart Collections I have.  There isn't any migration tool available and LR presets simply won't work in those other apps (as far as I know for Capture One; definitely not for ON1).

So I'm stuck unless and until LR gets worse than it already is.

Unfortunately posts do occasionally get missed at the time of posting, then disappear down the listing never to be seen again until someone bumps it.

So let's start with the basics - go to help menu > system info and tell us what's there, and then tell us exactly what you're finding so slow.
