Swappiness doesn't work as expected
you can fin below an extract of what I have on my droplet (Ubuntu 14.04.5 LTS):
System information as of Sat Apr 11 04:50:46 EDT 2015
System load: 0.01 Processes: 89
Usage of /: 62.2% of 19.56GB Users logged in: 0
Memory usage: 68% IP address for eth0: 18.104.22.168
Swap usage: 0%
root@droplet1:~# free -m
total used free
Mem: 993 834 158
-/+ buffers/cache: 668 324
Swap: 4095 0 4095
root@droplet1:~# cat /proc/sys/vm/swappiness
So normally, by setting up swappiness to 90, I should have the swap used as soon as more than 10% of my RAM is used, but it is not the case, someone already ran into that problem with DO? on my other stations it works good.
