Hm, not really sure what you mean here. There are quite a few knobs in 
Documentation/sysctl/vm.txt to tune VM related stuff. You could disable 
disk- or controller-caches - but why would you disable caching at all from 
a performance point of view? I'm sure you'll have the disk cache enabled 
with your real-world applications as well?
