+Is so slow in Amazon S3 !
+-------------------------
+
+Posible related to the implementation of your Amazon S3 Backend, see the issue `#351`_
+due the storage backend reviews if there is an existing thumbnail when tries to
+generate the thumbnail that makes an extensive use of the S3 API
+
+A fast workaround if you are not willing to tweak your storage backend is to set
+the `THUMBNAIL_FORCE_OVERWRITE` setting to `True` by default is `False`, so it will
+avoid to overly query the S3 API
