how do I see what memory is used and how much remains free and what is eating the memry. Since yesterday upgrade from Catalina to Montery (because of security warning) the machine is very slow. Some help pages suggest I have run out of memory but I do not know how to find if that is true in my case,or what to do about it. I wonder whether to return to Catalina , as none of the new features advertised are useful for me.

What are we talking about here...
Memory = RAM
SSD = Storage
Do some general house cleaning if you think storage is your issue

If you just upgraded the macOS— have you shut down and rebooted since the upgrade—sometime more than once helps the code settle in...
restart or shut down your Mac

My More Learned Colleague has offered advise to work thought the UpGrade issues and tend to work thought this before exploring the downgrade option
Below is the second part of your question and should not be entered into lightly.
Scorched Earth Method
This method will WIPE ALL Data and there is No Recovery - Period.
>> Only works on Intel Based Apple Computer
To perform this action will require booting from a Bootable Installer.
The Bootable Installer can Only be performed on an Apple Computer
This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer. Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.
Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.
Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
Extra Special Notation regarding the Touch ID equipped Apple Computer.
About Startup Security Utility and Must Enable from Recovery Mode the ability to boot from External Drive Before Attempting
1 - Shutdown computer and disconnect all external drive Except the newly created Bootable Installer.
2- Restart and immediately hold the OPTION key until the Startup Manager appears and choose the USB Drive.
3 - It will present options >> Disk Utilities >> View >> View ALL attached Drives.
4 - Choose the Upper Most Drive ( not the volumes indented and list below ).
5 - The drive normally is called Apple Media or Apple SSD - that is the drive to Erase and format as APFS with the GUID Partition Map. This applies to macOS 10.14 Mojave and above.
5A - Formatting for macOS 10.13 High Sierra and below requires HFS Journaled with the GUID Partition Map
6 - Once that is done >> backup out of Disk Utilities and choose install macOS.
7 - Follow the prompts and it may automatically reboot several time.
8 - Upon a final reboot - Setup Assist will present with the newer version of macOS.
