There is no much performance difference after I enabled the MASTER_READTITLE_ONLY flag on the clusters I used. I changed it to default for future release in case other users have same problems on a particular system. There could be a little negative impact if the network between compute nodes is slow, but that should be minor. As this flag will control how many cores read the tile part simultaneously, it might not affect the performance very much for a small number of CPU cores. The performance of I/O operations for the system should be examined for this case.
