The IO performance drops dramatically as the MPI-IO threads increases over 512. I am not sure where the performance problems lie. I am about to collect the IO requests to each OST to distinguish the problem of MPI-IO and Lustre. But I am not familiar with any Lustre IO monitoring tool. Any suggestions? 
Thanks in advance.
