The answer may depend on what device is at the other end of NDMP.
I was told that with NetApp NDMP that changing the buffer did not change
performance due to the way that the WAFL filesystem handled things.
It would be interesting to revisit this and see if they had made any
changes to enable larger buffers sizes improve performance.
Some of the other NDMP devices with different filesystems may show an
improvement.

Subject: [Veritas-bu] NDMP Performance
Anyone know anything about the SIZE_DATA_BUFFERS_NDMP touch file? Is
this even still valid? I can't seem to find anything about it in NBU
documentation, just a reference in the archives of this mailing list.
Is this worth investigating as a performance enhancer for NDMP?
