And found this article: How to use RAM as swap
Please try not start a flame war here, this is not the goal of my post. If you have some theory about why it is usefull or not please add your comments there.
(This is to somehow limit the extent of the war as I'm going to shoot first
I'm myself a bit surprised that such a thing could work but I would like to know if anybody tried this on his Z and if it has brought are some performance improvment or not.
I tried a little bit just now, and plan to do a bit more testing but I can't say I've seen any difference.
The only thing that is perhaps usefull is that Linux seems to use the swap as soon as there is one and not only when memory is full (if I understand cat /proc/meminfo enough). So that if you create a swap file on an sd card, Linux will start writing on it whatever you do. So by creating a swapfile in a ramdrive with a higher priority in a ramdrive and a second one with a lower priority somewhere on flash maybe the second one will be used only when needed.
anway I have added another point to my post counter
