Okay, I have read plenty of other forums before posting, including ones published by Adobe themselves obviously. I have tried every single fix mentioned. First off, my specs are fine, but you can find those below. For brevity's sake, it's an professional-grade custom PC on Windows 10. To name just a few off the top of my head: I've tried running LR with GPU acceleration enabled or disabled, no difference (although GPU is confirmed to be supported). I have 150GB of cache, didn't seem to matter. LR Software, cache, photos, and catalog are on a prosumer-grade SSD with plenty of extra space. Tried forcing app to run in dual-core, (but reverted back to multi-core when that killed my performance even worse).
No matter what I do, Lightroom is very slow. Rendering is fast enough I suppose, but developing is so sluggish. I render 1:1 previews before starting every new job, and it's doesn't even seem to matter. Adding radial filters, using the adjustment brush, straightening angles, and even adjusting exposure takes multiple seconds to see and register every change, I can't afford to work like this. By the way, my collections aren't thousands-deep, just a lit over a hundred photos at a time. Not sure if that'd matter or not.
I have seen tons of forum posts with users having the same issue as me despite many having similar to higher-spec PC's. My co-worker uses Lightroom 5 on an outdated Macintosh, and it runs much better than it does on my modern system with modern software. I don't get it? Is there something I'm missing here? Because I really don't want to be another one of those people who talk smack and say that Adobe doesn't care to streamline & optimize due to lack of competition.
SYSTEM SPECS:
Temperatures are just fine, memory, disk, and processor utilization never surpass a 50% load, even during long and intensive renders. Another note: Adobe Photoshop, and Premier Pro run pretty much great, I don't have any problem with these applications holding me up. If I can edit 4K video without proxy files, I should be well-equipped to handle to some pretty basic photo development.
Any help would really be appreciated, please and thank you.

No don 't do that. I was speaking about CPUs that have more than 4 Physical cores. Since your only has 4 you shouldn't, Should NOT, try to disable any of them.
Try turning off the GPU option on the Performance tab of the LR Preferences.
Also go into the Advance Power options of Windows and set your system to run at Max Performance to see if that helps.

Does your CPU have more than 4 cores? If it does LR doesn't work correctly with CPUs that have more than 4 cores. There is a way to limit LR to use only 4 cores, although I don't have a link to it.
Once you do that it will run faster.

The 6700K is hyper-threaded so it has 8 logical cores, and 4 physical cores. I will try disabling 4 of the other threads and see how that works, thanks for the tip!

Okay, thanks for the info though,
GPU off/ on doesn't seem to make a difference as mentioned in the post unfortunately. I've choosen to keep GPU acceleration off though because I've heard it doesn't do much for people who are on monitors under 4K.
Yeah, that power options Max performance trick is one of the first things I do upon Windows installs. I just checked and it's still set to max performance.

If you can check the BIOS/EFI settings as some contain a setting to limit the CPU speed. It is usually something like Intel Speed Step.

Hmm, I didn't really think about that, but again, I've already scrubbed through CPU related settings, I'm a bit of a PC enthusiast and was working with some manual overclocking not too long ago. I would have certainly disabled this setting. Also, while running benchmarks for gaming I get a constant 4.3GHz, so I really don't think it's throttling.

My i7-5930K is overclocked at 41, but I had not thought about Intel's SpeedStep slowing things down. So I just disabled Speedstep in the Bios, and LR is indeed more snappy; it wasn't slow before, but this may be the solution many need. I've also updated my Win10 to the Creators Update (preview) and that has made Win10 faster unless I'm imagining things.
A Happy Easter Bunny!

Yeah, unfortunately, even within the first 4 minutes it was noticeably worse. (at least in the develop module, which is my biggest gripe currently)

What is your display resolution? I picked up a 50" 4K tv that I use as a monitor. When plugged into my laptop, Lightroom is wickedly slow. I usually edit at 1920x1080 on the laptop display and Lightroom isn't bad. As a test, you might try to lower your resolution and see what happens.

My monitor is 1440p, which according to my research on LR shouldnt be too much of a factor, I have also tried setting lower preview settings as recommended to no avail.
