Do I need more RAM?

I have an iMac 2020 with 32GB RAM.

My question is if i need more memory, because I'm confused about the indicators of activity monitor, as shown below. If there is 'Swap used', does it mean the available RAM is insufficient and the machine would benefit from adding more RAM?

Because nowadays RAM is not expensive, I want to maximize the performance so I can add more 32GB if needed.

Solution 1:

You have a lot used, apps and "wired" memory using around 25GB, but you have nearly nothing using your swap file at only 400MB used.

If you had a significant amount of swap used then that would be a sign that memory is your problem, but low swap usage suggests that buying more more is not a high priority for your system.

The "wired" memory being high suggests to me that you just need to reboot your computer.
