I can give you quantitative data on the benefits of shared objects. On
a web server running FreeBSD 6.2 I found 98 shared objects sharing
16,790,901 bytes of memory through 1,002 mappings.
Without shared libraries the corresponding binaries would require
198,815,270 bytes - an order of magnitude more.
On freefall I found 58 shared objects sharing 11,285,262 bytes of memory
through 2,127 mappings. Without shared libraries the corresponding
binaries would require 515,107,268 bytes - 50 times more.
These are not just memory savings, but, more importantly on a modern
system, they contribute to improved locality in the code cache.
I've put the Perl script I used for obtaining these figures at
