Hi, I'm sorry in the last post, not romio_pvfs2_listio_write seems the right setting to use datatypes but romio_pvfs2_dtype_write Which is disabled by default as well...
When I set the hint it works, reducing the time from 0.07s to 0.003Xs so about 20 times faster due to the saved round-trips on our cluster. I verified the expected behavior in the trace files.
