+@subsection Automatic symbol index cache
+
+It is possible for @value{GDBN} to automatically save a copy of this index in a
+cache on disk and retrieve it from there when loading the same binary in the
+future. This feature can be turned on with @kbd{set index-cache on}. The
+following commands can be used to tweak the behavior of the index cache.
+
+@table @code
+
+@item set index-cache on
+@itemx set index-cache off
+Enable or disable the use of the symbol index cache.
+
+@item set index-cache directory @var{directory}
+@itemx show index-cache directory
+Set/show the directory where index files will be saved. By default, the index
+is cached in the @file{gdb} subdirectory of the directory pointed to by the
+@env{XDG_CACHE_HOME} environment variable, if it is defined, else in the
+@file{.cache/gdb} subdirectory of your home directory.
+
+There is no limit on the disk space used by index cache. It is perfectly safe
+to delete the content of that directory to free up disk space.
+
+@item show index-cache stats
+Print the number of cache hits and misses since the launch of @value{GDBN}.
