James,

Should we consider, that such a difference is normal. You suggest that before
the kernel was dangerous at writing data?
So unpacking linux kernel (for example) is 5x times slower and it is not a
problem. That's just new way of caching data? We seldom see crashes (thanks to
linux) and we have power supply.

I'd like testing on same hardware windows to see its behaviour and speed.
Anyway thanks for the clarifying of cache: write through. As you say, it was
not evident. 

So, now, what can we do to keep 2.6.21 behaviour? That's for a mail system
writing lots of little files and performance matters too.

Dom
