ldconfig is called in very large amount of package dpkg postinst scripts. These take many minutes to run per package on older systems, and a system upgrade is painfully slow unless one moves /sbin/ldconfig out of the way (since it appears completely unnecessary in all usage I have encountered to date) and symlink to /bin/true. It really shouldn't be taking that long, and that thread mentions adding an argument to ldconfig to get it to only update the files in question, rather than updating the symlinks and cache for *everything* that appears in all the lib directories. In the case of the cache, you don't need to look at the existance and location of every library on the sytem, just assume they are correct from the entries already in the cache -- only add and modify those from the arguments supplied. Since the dpkg and necessary policy changes don't look like they are going to happen any time soon (I've been eagerly awaiting a proper solution to this bug for 6 years), could the libc maintainers think about adding this argument to ldconfig?
