It looks like my network speed is like a bell curve. Going up steady to
about 700MBit then slowing coming down to 129MBit. Then it starts to go
up then down again.
Could be my network. Need to do more checking.
I just did some more test but with a larger transfer of data and it looks that
the ethernet connection is good. So the NFS is still the problem.
Please comment or suggest.
Below is the test results.
