I don't know what you are doing in real conditions but i am for sure not only running everything in my RAM (that'd be great, i wouldn't even need a harddisk anymore). The benchmark needs to be revised to account for the VM caching or it's just useless. Or rename it to "benchmark of memory access and caching algorithms".
