Side note: it might be even more advantageous to use bsdiff instead of xdelta3 comparing the /usr/bin/blender binaries of the above versions (12:2.69.c7ac0e-1 and 13:2.69.13290d-1) :
xdelta3 10.4M xdelta3 -9 9.9M bsdiff 4.7M
I took a look, and changing from xdelta3 to bsdiff would be very simple. It looks like it is a five minute patch... But what I need is for someone to generate deltas (with and without -9 maybe) for a whole bunch of packages. Then generate diffs using bsdiff and compare the results. The comparison will need to include: 1) size of deltas/diffs 2) memory used when reconstructing package 3) time taken to reconstruct package. Once we have that information, we can make an informed decision. Allan
