3G RAM + 1G Partition Swap - is it enough?

It’s worthwhile also setting the overcommit to the more generous setting: you’ll find it’s already noted in your upgrade log, if you haven’t already adjusted it

WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add ‘vm.overcommit_memory = 1’ to /etc/sysctl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1’ for this to take effect.

This has been mentioned many times before but there’s resistance to adding it to the standard Discourse installation recipe.

I mentioned this as soon as I first installed Discourse (Warnings: overcommit_memory and Transparent Huge Pages). Why is it worthwhile doing and what is the reason for resistance? I haven’t changed the default setting.
