MATLAB R2023a unusable on brand new desktop computer

I recently bought a brand new computer to replace my outdated system:
  • AMD Ryzen 9 5950X 16-Core Processor 3.40 GHz
  • NVIDIA GeForce RTX 4070 TI GPU
  • 64GB DDR4 3200 MHz RAM
  • 4 TB SSD
  • Windows 11 Home
While MATLAB R2023a (and all of my scripts) runs flawlessly on my previous home desktop as well as my work computer which feature 1/4 the RAM and far worse specs - doing absolutely anything in Matlab on my new computer is like pulling teeth. Not only does my code run at a snails pace - such that it basically seems like Matlab is stalling half of the time - but doing simple things like opening variables in my workspace can take 5-20 seconds when normally this "feat" occurs instantaneously on more antiquated systems.
All of the other software i've installed on my new computer runs as you would expect on a high performance computer so the issue appears to be with MATLAB specifically. Thank you in advance for any suggestions for solving this issue.

This is not exactly an "answer", but my advice would be to re-install, and if that doesn't help contact Mathworks support.

I have encountered this problem when I installed R2023b. I use previous version instead (R2020a). Perhaps you should do the same.

Use Windows Task Manager and Resource Monitor to see what else is running and what resources are being used.
Also R2023b is currently available to download and install.

Thanks @Star Strider, I didn't know about the bench program. Below are my embarassing results on my 12 year old, Windows 10, Core i5 system. Looks like I need a new computer! 🥵

My pleasure!
For this computer (about 3 MHz during that run).
