I appreciate the slight improvements made to LR over the past year or two but the one I'd really like to see improved upon is the unbelievably sluggish tone curve (Windows 10, GTX 1070, i7 @ 4.5GHZ, 4K). Why can't this be easily fixed, I'd really like to know.
Working with Canon & Fujifilm Raws, Phase One TIFFs (slightly better with these files but not by much).

Actualy, it can also be viewed as, why is the OP having performance issues when using the tone curve

It is so frustrating to have issues in newer faster more capable computers. My rig is not as capable as yours (at least a slower CPU, oh, but to be fair my GPU is the 1070 Ti) and I do not have these issues with tone curve, or for that matter adjustment brushes. Mind you, while I do have a 4K display, I normally run it at 2K res.
But moving on
As your OS is Windows, and as such you can reduce your display resolution, do you see better performance in the tone curve response at the lower res?
Yes, I know, you did not spend big bucks to run at 2K. Try this as a diagnostic step

So, looks all fairly up to date.
Display at 4K, so some performance issues can be especred, hopefully the new GPU acceleration would take care of
Lightroom is using DirectX, so no issue their. check
GPU driver up to date, check

Did not, I think, provide one link. This on performance of NVIDIA GPU’s. Apparently not all issues/solutions for Lightroom performance revolving around the GPU are caused by Lightroom settings. Apparently can cause Lightroom to deny acceleration.

Thanks for your help, David. I suspected the GPU power settings a couple of years ago and changed this to your link's recommended settings already. Despite my GPU settings in LR set already to 'auto', I changed to 'custom' anyway. My cache is already set at 40GB on the same internal drive as the catalogs reside (ssd sata which is always at least 1/3 free space), independent of the OS m.2 ssd.

May want to contact Adobe. Usually the issue is with adjustment brushes slowing down, and everything slowing down after several brushes have been applied. Always with 4K or 5K. But the tone curve sluggish? Odd.

Hi David, I found a solution to this problem - I found it on a reddit thread that's linked within one of the tone curve discussions in this forum. The problem stems from having too many tone curve presets. I temporarily changed my tone curve presets folder's name so that LR couldn't "find" it. The tone curve is responsive and fluid now. Unfortunately for all of us, Adobe devs haven't found a way to let us keep all our presets intact without affecting the performance for some reason. This is really strange. as the tone curve functionality should be in no way affected by the amount of presets available to it. This is akin to selling us a Porsche but in the same breath telling us to "always keep it under 80 km per hour.
Would those presets be develop presets?
Just how many do you have?
An occasional performance issue can occur if you have too many develop presets visable, I think the issue occurs if in the hundreds, perhaps thousands. Solution is to not relocate or delete some presets but to manage the visibility of them in the presets panel (right click/manage/ check on or off as you see fit)
hmm, was looking for a link, this one actually reccomend what you did:
