[ wild speculation ... ] How does it decide what to copy? If it is a "blind" make-me-a-package tool it may be scanning the whole OS install or something (expensive but linear) and maybe then doing some ghastly O(n^2) changed file comparison. Inefficient comparison stuff leaks into the real world all the time; the Linux kernel installs have a "hardlinks" program which is one of my pet hates for this very reason - it runs over the modules trees looking for identical module files to hard link and if you've got several kernels lying around it is unforgivably slow. Or maybe it loads the package install db into memory and does something expensive to see what's not accounted for.
