I have a swap file
/swapfile of 1GB size in accordance with the procedure described in the ubuntu swap faq.
When doing a RAM intensive task, I use the "System Monitor" to check the load on my Memory and my Swap. When the task is done, the Memory load goes down quickly ... however, the Swap load stays high for a very long time and only trickles down very slowly (see image).
sudo swapoff -a && swapon -a, I can clear the Swap manually ... but I'd rather know:
- Why is Swap taking so long to be cleared?
- Is this impacting the performance?
