LTIB Image file size estimation and NAND Compression techniques.

Dear Support,

   is there an estimate available on the actual root image file sizes when LTIB is built for a specific architecture. I understand the PDK comes with 2GB NAND. Is there a rough guide on the kernel and the rootfs filesizes in advance?.

net@net-PC:~/Qt_imx257/ltib/rootfs$ ls -lh root*

net@net-PC:~/Qt_imx257/ltib/rootfs$ cd ..
net@net-PC:~/Qt_imx257/ltib$ ls -lh root*
-rw-r--r--  1 net net  15M 2011-09-13 21:56 rootfs.cramfs
lrwxrwxrwx  1 net net   15 2011-09-13 21:56 rootfs_image -> ./rootfs.cramfs


Is the current filesize seen for the Image correct?. I have been unable to find resources to compress/compare various image formats. Could someone provide any specific document on this?.
