+\item[Keeping Tag Cache on disk.] This does not require extra RAM for the
+Tag Cache and speeds up the boot process, but is slower when accessing.
+\item[Keeping Tag Cache on disk with Dircache enabled.] With Dircache
+enabled updating of the database is much faster. Also updates can be
+committed in background immediately.

+Directory Cache in General Settings $\rightarrow$ System $\rightarrow$ 
+Disk $\rightarrow$ Directory Cache.}
