+### Fingerprinting
+
+Various parts of the VFS use fingerprinting to see if a local file
+copy has changed relative to a remote file. Fingerprints are made
+from:
+
+- size
+- modification time
+- hash
+
+where available on an object.
+
+On some backends some of these attributes are slow to read (they take
+an extra API call per object, or extra work per object).
+
+For example `hash` is slow with the `local` and `sftp` backends as
+they have to read the entire file and hash it, and `modtime` is slow
+with the `s3`, `swift`, `ftp` and `qinqstor` backends because they
+need to do an extra API call to fetch it.
+
+If you use the `--vfs-fast-fingerprint` flag then rclone will not
+include the slow operations in the fingerprint. This makes the
+fingerprinting less accurate but much faster and will improve the
+opening time of cached files.
+
+If you are running a vfs cache over `local`, `s3` or `swift` backends
+then using this flag is recommended.
+
+Note that if you change the value of this flag, the fingerprints of
+the files in the cache may be invalidated and the files will need to
+be downloaded again.
