: If I have saw 20 instances of an executable with 100 shared
:libraries, or 20 instances of an executable with 5 (much larger) shared
:libraries, or 20 instances of a very large mostly static executable,
:what is the relative memory hit? Or swap hit? My test may have been
:too simple.... How different would the answer be in Linux?

: (This is for working on figuring out how much of a win it is in
:Mozilla to combine shared libs, which some people are working on.)

However, I would say that for something like Mozilla linking static is
going to be a definite win since nearly all the libraries referenced
by Mozilla are special purpose - going to be used primarily by
Mozilla and not much by anything else. If libX11. There isn't much
there that would be shared enough to make it worthwhile vs the memory
overhead of the dynamic linking.
Having lots of tiny shared libraries is a definite lose, but once a
shared library gets over a few hundred K continuing to merge it with
other shared libraries isn't going to buy you much vs what you would
get with static. One might as well just link static.
