My company is working on the cutting edge of 6K+ stereoscopic 360 VR. We have gone through great lengths to purchase the most powerful PCs available on the market for the sake of faster performance. Unfortunately we're faced with the bottleneck of your software not utilizing this modern technology. Simple tasks are literally taking days, and at times weeks because of this. At all times, Windows Task Manager is showing After Effects utilizing less than 10% of both CPU and GPU. We have spoken at length with multiple reps from Adobe, Mocha, After Effects and Microsoft to confirm our settings are optimized, and they are. Everyone is in unanimous agreement that it is the coding of your software that's dragging us down. Adobe should be aware they are currently the weakest link in the chain. We enjoy using your software, but we are also unsatisfied with your level of progress.

Oh look! I built a new workstation! (Specs: https://pcpartpicker.com/user/Cx/saved/gWRk99 )
What's amazing: Cinebench scores are fantastic! Lowest rendering time (quickest!) of the many years I've been running the AE Total Benchmark scene! Everything else I run other than AE is much improved!
What's not amazing: AE previews are still slow and the UI is laggy. And there's seemingly nothing I can do about it.
PugetBench results: Overall score of 1156. (The School of Motion article listed in the response from Victoria Nece shows a score of 985.)
CPU-Z benchmark results: 16336 (multi thread) / 499 (single thread)
I am beyond frustrated at the state of this application. It is, without hyperbole, the greatest pain point in my professional life.

I'm having the same problem.
AE's Ram Preview and Render Queue renderings are often super slow but AE barely use my available hardware resources. Most things seems to render only on one CPU Core. Even the GPU is mostly doing nothing although Adobe claims that they are porting more and more effects to be GPU accelerated. My personal opinion is they should better invest development resources in multithreaded CPU Core rendering and porting ALL EFFECTS to be 32bits per channel color aware.
Also think about AMD's next Threadripper 3 CPU offerings with hopefully 64 CPU Cores coming in Jan. 2020!
AE's RAM Preview is often only capable of rendering with 0,03 fps but my 16 CPU Cores idling between 10%-50%, GPU is about 5%! When I render something with other software e.g. 3ds max and Arnold renderer CPU is maxed out 100% all the time! AE's performance is getting worse with every release - it's ridiculous.
And if you work with large footage files and compositions (4K, 8K) having "Mercury GPU Acceleration (Cuda)" turned on in Project Settings AE renders slower then when turned off ("Mercury Software only")!
If you activated in Preferences -> Display:
"Hardware Accelerated Composition, Layer, and Footage Panels"
The whole UI gets sluggish instead of snappier - This UI GPU Hardware acceleration seems to not work either very well and is one reason people complain so much about UI performance in general. So I suggest turning it off.
My System Specs are quite fast but Adobe is still crawling:

There is already a major thread for this and a comment from the dev team.
