Doc Text:
In a two node cluster, the lock master of two folders can move 100 files from one folder to the other in less than 1 second. If a server is not the lock master for that folder, it would take that server 3-5 seconds to perform the same task on GFS1 (Global File System 1), and 30-50 seconds on GFS2 (Global File System 2). With this update, the aforementioned task takes less than 1 second on GFS1 and about 3 seconds on GFS2.
