[lxc-users] Container scaling - LXD 2.0

Greetings all,

I am trying to get some data points on how many containers we can run on a single host if all the containers run the same applications (eg: Wordpress w/nginx, php-fpm, mysql).  We have a number of LXD 2.0 servers running on Ubuntu 16.04 - each server has 5G RAM, 20G Swap, and 4 CPUs.

I have read about Kernel Samepage Memory (KSM), and it seems to be included in the Ubuntu 16.40 kernel.  So, in theory, we can over provision our containers by using KSM.

Any pointers?
