Value is different today but still some losses.  I'm trying to identify the source of a report creation that is taking way longer than is should overnight and starting from the network up.  This port is part of my data network that is directly connected to my ESXi hosts.

Thanks Daniel,

I'll gather the metrics and post my results.

So......there's not really a great deal going on that is raising any alarms for me... An example output using rmon is:

Looks ok to me but I could be missing something.  I noticed some input and crc errors on the other end of this connection but again they are very small (513 and 384).  I doubt that would be causing the hours being added to the job run in question...... i'm now monitoring various bits and pieces on the VM itself so will see what that produces....  

software version is 6.2.0.5

I noticed that flow control was enabled on the up links to the cisco stack and im having difficulty deciding if its having any impact.  I understand what it does but I'm not seeing any evidence of buffers filling up on the cisco stack or any failures.  Got 11MB per second when transferring a  600MB file across the data network.  Way too slow.

Thanks Daniel,

Not convinced there is a problem now. Might just be a poorly configured network segment.  I'll do some more testing.  Thanks again for your help on this!
