--- Doc Text *updated* ---
Before a file operation starts, a lock is placed on the file. The lock remains in place until the file operation is complete. After the file operation completed, the lock remained in place either until lock contention was detected, or for 1 second in order to check for another request for that file from the same client. This reduced performance, but improved access efficiency. This update provides a new volume option, disperse.eager-lock, to give users more control over lock time. If eager-lock is on (default), the previous behavior applies. If eager-lock is off, locks release immediately after file operations complete, improving performance for some operations, but reducing access efficiency.
