Explanation

The output from free -m shows that a significant portion of the swap space (955 MB) is being used, indicating the server is swapping. Swapping occurs when the system runs low on physical memory, leading to poor performance because the system must offload memory pages to the slower swap space. To resolve this, either more physical memory should be added or the application's memory usage should be optimized.
