That's not really much of a difference (saves only about third). 
In Maemo they would be both considered bloated no-gos.

It would seem that in both archivers the memory grows linearly compared to
the archive size, is this right?   I.e. both use O(1) algorithm, which is
a clear mistake if one wants to deal with larger amounts of data.

What makes this even stranger is that Zip files have the index separately at 
the end of the archive unlike e.g. tar(.gz) files which don't have an
index.  Where these programs are wasting the memory, I'm pretty sure
InfoZip (the command line tools for handling zip files) doesn't have this
issue?
