This might explain it: https://bugzilla.redhat.com/show_bug.cgi?id=156477 The mmapped local-archive contains all languages even though only the ones you use are accessed from it. Other distros split them and the installers only install what you want. > 64 bit system: > 00007f8ae84b7000 102580K r---- /usr/lib/locale/locale-archive > > 32 bit: > b7689000 2048K r---- /usr/lib/locale/locale-archive That's an interesting difference on its own, since the underlying files are about 95M and 54M respectively. Does the 32 bit kernel use some tricks to sparsely map files where the 64 bit one does it directly with page tables? -- Les Mikesell lesmikesell at gmail.com
