✅ Step-by-Step Guide:

Clear RAM Cache:
Choose a lighter or deeper cleanup:

sudo sync && echo 1 | sudo tee /proc/sys/vm/drop_caches
Tip: Use echo 1 for a lighter cleanup (cleans PageCache) or echo 3 for a deeper refresh (cleans PageCache + Dentries + Inodes).

Reset Swap Memory:
Disable swap, move data back to RAM, then re-enable swap:

sudo swapoff -a && sudo swapon -a
What it does: Disables swap, moves data back to RAM, and re-enables swap for better performance.

Check Memory Usage:
Use free -h to view available memory (not just free):

free -h
Tip: Look at available memory to assess system performance.

✅ Why Free Up Memory?
Boost Performance: Free up RAM and swap for faster system response.
No Downtime: Instantly improve performance without rebooting.
Safe: Doesn’t close running applications.

✅ Pro Tips:
Use After Heavy Programs: Best used after large programs finish to reclaim memory.
Monitor Usage: Regularly check memory usage with free -h to stay ahead of performance issues.
Combine Commands: For a full cleanup, combine commands in one line:

sudo sync && echo 3 | sudo tee /proc/sys/vm/drop_caches && sudo swapoff -a && sudo swapon -a
