Abstract
A method is used for improving performance in a storage system during deduplication. A processor receives a request to write data. A determination is made that the data can be deduplicated. A non-exclusive lock for a page in storage with a reference count of the data may be obtained, and an instruction to increment the reference count for the data may be stored in a metadata journal. The non-exclusive lock for the page may be released.
