L3 cache sits on the same chip as the CPU, its incredibly fast and usually pretty small (96MB in this example). This software turns that little bit of memory into a ram disk. Why not make the L3 cache bigger I hear you say - cause its expensive.
Also, the cache is usually used for code so if you use the cache for data your software will run slower.
