Update: I figured out where my problem is occuring... I have lots of calculations in my doc., and performing calculations seems to have gotten orders of magnitude slower. Turning off Preferences->Forms->Automatically calculate field values restores the speed, but at the cost of some of my field updates not taking place...
But this comes from an Acrobat Pro change; files created & not touched for years are now much slower than they ever had been.
Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive please download it to your computer locally and then try again.
What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 22.3.20281 (Mac) installed. Go to Help > Check for updates and reboot the computer once.
You may also try to create a new test user profile with full admin rights or enable the root account in MAC and try using the application there and check.
I'm having the same issue - started several weeks ago. Nearly EVERYTHING I do with Adobe Acrobat Pro is incredibly slow. Cutting & pasting text from one field and putting into another - takes seconds. Clicking a button to run custom Javascript code - consumes seconds.
I'm running Adobe Acrobat Pro "Continuous Release | Version 2022.003.20258". When I try to do an update (e.g. to .20281 as suggested above), I'm told I am in fact running the latest version.
I'm running on the 16", 2021 model MacBook Pro with M1 Max chip, 64GB of Ram, and macOS Ventura 13.0.1. As suggested in a different support discussion, I have updated Preferences->Page Display->Rendering->Use page cache to turn that setting off, followed by reboot. Perhaps there is a 5-10% speed improvement; still incredibly slow and the smallest of page updates takes seconds. Scrolling, however is fine. Perfectly snappy there. It's any time a form field is edited that we drop into incredibly slowness.

Same issue.. just trying to type takes literal seconds of lag for the text to show up. No funny stuff like tables or anything.. just text. Can i even revert to an old version now that i'mon the continuous release? MacBook Pro M1 Pro Chip OS is Sonoma 14.3.1 Acrobat Pro version: Continuous release V 2023.008.20555
Have searched all the forums, tried all the fixes, includingh the one listed here in green. It still demands 99.3 % cpu. Worst when resizing the main window.
M1 pro, 32gb ram, 16 inch MBP.
Have tried multiple different small files, reinstalling, updates etc etc etc. you name it, i've tried it. Seems to be an issue with Acrobat software itself.
Please fix... it is certainly not ideal for paying customers.
Would you mind sharing the version of the Acrobat and the OS you are using? To check the version of the application go to Help > About Acrobat and make sure you have the latest version 23.06.20320 installed. Go to Help > Check for updates and reboot the computer once.
