Adding a swap partition: advice / data?

Posted February 28, 2014 2.7k views
I'm running a CentOS 6.5 droplet, and am wondering if I should add a swap partition. I know just enough about this stuff to think that the answer is "well, of course", but I don't really have a foundation for going beyond that. Will my system just die the first time it gets seriously loaded up with users and memory demands? Will swap save me from that, but only by imposing an unpleasant performance hit? Any advice in this area would be greatly appreciated.

See https://www.digitalocean.com/community/articles/how-to-add-swap-on-centos-6 to setup your swap file.

Since DO uses SSD disk drives you don't take near as big hit when swap is actually being used.
