vmstat-10Gb.log (NOT OK - System Unresponsive)

I now drop back to 10Gb of RAM to test the swapping under 4.11.x kernel.

Log attached as vmstat-10Gb.log

Timestamps:
22:10:00 - Launched of the game from within Steam
22:11:00 - Load the same saved game from the previous log
22:12:01 - Saved game is loaded and I can scroll around. Noted a slight
pause when swapd went to 256 - but otherwise all is well.
22:13:00 - Launched Google Chrome browser to make the system swap.

After this point, the whole system went to hell. You'll note many missing
vmstat entries up until around 22:22 when I managed to exit from the game
back to desktop via the normal means (and not getting annoyed and doing a
pkill from tty2).

As such, the system went nuts for ~9 minutes until I was able to exit the
game to stop things going nuts.

I note that with 20Gb RAM - as the system never touches swap, I can still
play the game, browse the web with the Chrome browser, read / write
email, and even watch a DVB-T broadcast in VLC without having any more
than a minor pause in the game for less than a second.
