Oplock

An opportunistic lock (oplock) is a key component of the SMB protocol that improves file access speed. It allows clients to cache and prefetch data locally, which reduces round trips to the remote server. This feature is particularly useful for single-user read/write operations, multi-user concurrent access, IIS servers, genomics computing, and shared map applications.
