Long, long time ago, in ancient Rome there was a sentence - "divide and
conquer". Unfortunately I did not see this aproach used while it helps
most of the time.
Why not to isolate each part of the data route and ensure it is working at
best possible throughput? This might help to identify the bottl
Some things to try:
1. verify that the MTU is consistent for all nodes, from your cws:

That seems terribly slow. 430 GB in 14 hours is only 8.7 MB/s aggregate throughput.
Over four streams that's only 2 MB/s/stream. It has been my experience that the source
hdisks are usually the bottleneck.
There are only two tunables for the switch adapter, rpoolsize and spoolsize.
These can be
