You are very right about this one.

Well, according to squid the page faults were due to physical writes but
I can't tell for sure yet. I guess I can try and test it and see what
happens. If the percentages are that small then it most definitely isn't
worth the trouble at all. My estimated guess was that the numbers would
have been greater than just 2-3%. Knowing though how easily an async
file system can corrupt, is there the slightest chance this could happen
under normal but heavy usage?
