+file system.
+The filesystem stores both file metadata and data in main memory.
+This allows very fast and low latency accesses to the data.
+The data is volatile.
+An umount or system reboot invalidates it.
+These properties make the filesystem's mounts suitable for fast
+scratch storage, like
+.Pa /tmp .
+.Pp
+If the system becomes low on memory and swap is configured (see
+.Xr swapon 8 ),
+the system can transfer file data to swap space, freeing memory
+for other needs.
+Metadata, including the directory content, is never swapped out by the
+current implementation.
+Keep this in mind when planning the mount limits, especially when expecting
+to place many small files on a tmpfs mount.
+.Pp
+When 
+.Xr mmap 2
+is used on a file from a tmpfs mount, the swap VM object managing the 
+file pages is used to implement mapping and avoid double-copying of
+the file data.
+This quirk causes process inspection tools, like
+.Xr procstat 1 ,
+to report anonymous memory mappings instead of file mappings.
