Use ramfs rather than tmpfs in RAMDisk.

So, I hope I know what I am doing, and will now use ramfs from here on.  On the Pi, there is a lot less free memory, but will leave some room below the free memory limit.

You'll be fine as long as you make sure you don't run of RAM, which is kind of OK with computer playback.

Do not be influenced by lower latency is always better mantra. It's more about the profile, which really isn't possible with a normal cyclic test. You'll really need to bin the latency into "bins", and look at it from a frequency domain, i.e. cyclicscope. I hope to implement this in the WebApp some day, unsure when though. That will be more useful, however we should also avoid the "is better" concept, as this is just one variable of a somewhat complex (if not outright chaotic) puzzle.
