Not correct. “Free” memory doing nothing is **bad**. But “available” memory is memory being used by the system that can be easily freed is a **good** thing. 🙂

Or officially:

> Available memory: Estimation of how much memory is available for starting new applications, without swapping.

Source: `man free`

As per the screenshot below, free memory is just about unchanged. So nearly all of the system’s memory is being used. However, the system will swap less now because there’s more **available** memory that can be freed when needed.

…yes, I prefer to free up memory if not being used until such time traffic requires any changes.

thanks again.
