This patch applies zlib compression over our glz compression on low bandwidth connections (reminder:
glz compression is applied over images that are classified as artificial/textual).
It improves the compression size, though it consumes more cpu on the server side (hence,
it is more suitable for low bandwidth connection). Total improvement in the size of data compressed by GLZ is ~20%-35%.
zlib windows libraries can be downloaded from:
http://www.winimage.com/zLibDll/zlib123.zip (for the version in fedora)
http://www.winimage.com/zLibDll/zlib125.zip (for the last version)
See the directory dll32.
Still need todo:
add an option via qemu to disable/enable the zlib wraparound.
