Setting swappiness for a single process
 

Anyone have step by step on how to setup and control swappiness on a single process.

I've seen some google articles talking about cgroups but since I don't even have cgroups setup...

A doc with a start to finish would be nice, if one exists. Any one know if such a doc exists out there?

probably I misunderstood, but for me it looks like it has no any meaning. swap is used to move some parts of memory out of RAM to be able to use it for "more important" processes. So if your process is not running (=waiting for something or similar) it can be swapped out, and will be automatically copied back to memory if required.
there is a renice command to rule the "importance" of a process.

"Swappiness" is a global setting which influences the system's propensity to swap. It ranges from "avoid swapping at all costs" to "aggressively swap." It is not a per-process parameter.

Could you use LXC to run a single process and set the swappiness in the container to affect only that process? Or docker, whatever.

It may be possible to write the program to set how it uses swap too.

i think op needs to explain all this much better:
and what they think they're going to achieve with it.
