If you are using a tmpfs ramdisk you will not waste memory. The more
data is written the more of your capacity will be used and memory will
be added dynamically (and freed when capacity not used anymore).
Make sure you have the swap to back up incase of memory starvation (ie
so your tmp will not wake up the OOM monster).
Usualy for every 1Mb of tmpfs I add I add 1Mb of swap, nearly never gets
used but diskspace is cheaper than RAM and at high memory usage (the
tmpfs will get swapped out usualy) the "ramdisk" performs slow but will
not crash ur system.
See http://en.wikipedia.org/wiki/Tmpfs for more info on Tmpfs, stay away
from the traditional ramdisks (just eating up ram and all, with no swap
Hope it helps
