I did try doing that but it is the copying part that takes plenty of time/cycles.Moreover, the writes in the for loop go thru' the buffer cache...maybe I could change this to a static address of the kernel memory and avoid the buffer cache;sounds like raw I/O.Does anyone know where the ramdisk is loaded after the unzip/load process?Where does it exactly fit in? p;n > -- > "In time of war, the laws are silent." -- Chief > Justice of the United > States Supreme Court, William Rehnquist > > ATTACHMENT part 2 application/pgp-signature __________________________________ Do you Yahoo!?
