gtk-update-icon-cache - 3.24.38-2~deb12u3pureos1 main

gtk-update-icon-cache creates mmap()able cache files for icon themes.
.
GTK can use the cache files created by gtk-update-icon-cache to avoid a lot
of system call and disk seek overhead when the application starts. Since the
format of the cache files allows them to be mmap()ed shared between multiple
applications, the overall memory consumption is reduced as well.
