In an approach to optimizing metadata management to boost overall system performance, a cache for a storage system is initialized. Responsive to receiving a cache hit from a host cache during a host I/O operation, a first metadata of a plurality of metadata is transferred to a storage cache, where the first metadata is associated with a user data from the host I/O operation, and further wherein the first metadata is deleted from the host cache. Responsive to determining that the storage cache is full, a second metadata of the plurality of metadata is destaged from the storage cache, where the second metadata is destaged by moving the second metadata to the host cache, and further wherein the second metadata is deleted from the storage cache.
