Thanks Cedric, I was thinking about that too. And since swapping is not
so desirable in such an environment you can lower the swappiness. But I
guess that may conflict again with your /tmp being on a temporary
filesystem.

Actually I have no idea what the programs I run do in /tmp. And given
the fact that apparently some people had more issues (xruns) with the
default swappiness of many systems than with a /tmp on a physical disk
I'd assume not mounting /tmp to tmpfs would be a better option. Unless
you got like 16Gb of RAM. Which I don't have.

Best,
