+## How to speed up bucket deletion?
+
+One common unexpected problem is the deletion can be slow. To delete a file, we need to delete the file content on the volume servers and delete the file entry from the filer store. It is almost the same amount of work as adding a file. If there are millions of times, it can take a long time to delete.
+
+If you need to create large buckets and delete them often, you may choose `leveldb3` as the filer store.
+
+`leveldb3` can automatically create a separate LevelDB instance for each bucket. 
+So bucket deletion is as simple as deleting the LevelDB instance files and the collection of volume files.
