 Which raises the question if simply adding the RAM to the system thus
 increasing the disk cache (and not dedicated to just one part of the app
 and - given the above description - wasting 50% of it almost completely,
 not considering fault-tolerance and similar) won't be as good (if not
 batter)´?

Any cache is going to have to hit the disk at some point, and disks are many orders of magnitude slower than RAM. Moreover, coordinating that effort of periodically hitting the disk would really, really slow things down. Using pure RAM really will be more effective.
