Monterey too slow

Thank you taking the time to post the Report.

The Biggest Issue, as I see it, is the Mechanical 5400 RPM Internal Drive. This may have been good in older versions of macOS but one reaching Catalina and above - it will be a real bottleneck to performance.

Alternative to getting some real performance, get a Reliable External SSD Drive and use that Drive to install Monterey onto it.

Then set the External SSD Drive as your Startup Drive.

disk0 - APPLE HDD HTS541010A9E632 1.00 TB (Mechanical - 5400 RPM)

Other issues listed below bear consideration

Major Issues:

Anything that appears on this list needs immediate attention.

Perhaps a more in-depth look at the relationship between computer and the installed software. For that purposes >>>

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.

Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.

This includes AntiVirus, Disk Cleaners, Disk Optimizes, UnInstaller etc.

The The Built in Security  is all that is required.

Before exploring the Revert to Previous Working macOS. - perhaps some details regarding what is not right with the computer.

Devil is in the details but may assist in determining where the issue are with this computer and Monterey

Agree on you points made.

Akin to selling laptops with very small 128 GB SSDs - almost useless for any meaningful use IMHO.

Best moving forwards with the reconfiguring of machine.

Do come back to the ASC Forum if or when additional questions arise.
