Hi KernelNewbies! Why are shared libraries hold multiple times in memory even if two processes uses the same libraries? I've made a little test with firefox and epiphany both are using the same SO --> /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so. Anyway if I look into /proc/$PID/maps of both processes I can clearly see that the library is hold multiple times in ram: firefox libs --> pango 2aaab9e49000-2aaab9e4b000 r-xp 00000000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so 2aaab9e4b000-2aaaba04a000 ---p 00002000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so 2aaaba04a000-2aaaba04b000 r--p 00001000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so 2aaaba04b000-2aaaba04c000 rw-p 00002000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so Epiphany libs --> pango 2aaab6287000-2aaab6289000 r-xp 00000000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so 2aaab6289000-2aaab6488000 ---p 00002000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so 2aaab6488000-2aaab6489000 r--p 00001000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so 2aaab6489000-2aaab648a000 rw-p 00002000 08:02 7604731 /usr/lib64/pango/1.6.0/modules/pango-basic-fc.so Please see the address differs which results that the library is hold multiple times in ram.
