Acrobat Search Feature is severely slow

Hello,

Thanks for any guidance on this issue.

We have four computers that search within a specific PDF. There are issues with two of these computers doing the search within this PDF. All four computers are exactly the same. They all have Windows 10 21H2 and are all have the latest Windows Updates. All four have Acrobat Pro DC 64 Bit and I have verified that all 4 have 23.001.20143.

The PDF has 5934 pages but is only 7.37 MB in size. The PDF has OCR recognition.

All 4 computers are Windows 10 21H2 and are using Acrobat DC 64 Bit.

What I have tried;

1. Updating to the latest updates of Acrobat Pro DC.

2. Uninstalling and reinstalling Acrobat Pro DC (with a running the cleaner and a reboot in between)

3. Making sure that we were using Fast Find and Purge Cache Contents

4. Turned off Cloud Based Search

5. Logging into system with account that has not been on the computer previously. After one fast search of the document, all consecutive searches run slow of the search of the exact same file.

6. Deleting the Adobe profile folders for Acrobat Pro DC - this allows one very quick search of the file and then it runs slow when searching the file again

7. Embedded Index the document. This stalls out at 14%.

8. Reimaging one of the laptops

I am at a loss to what is causing this issue. The two that have no issues are set with the same default settings as the other two systems.

Thanks, 

John
