Group,

 BEHOLD!  I have invented the NETWORK DOUBLER!  

Ok, thank you for indulging my attempt at humor.  I've fixed one problem and I'm moving on to another that is vexxing me since last week ( I think it happened when I converted my older mesh config and maddash.yaml files using the psconfig agents.).  Maddash now reports twice the bandwidth that the toolkit host does for the same test.  See here:

vs:

In fact, Maddash is reporting 2x the bandwidth that the NIC on the testing machines are capable of.

Because it's only affecting Maddash, I suspected the problem is with the Maddash.yaml file, or something else related to the dashboard.  But if there's a problem with the maddash.yaml, I can't see it from reading it.  Anyone have any ideas where I should be looking,  or tips as to what might cause this?  I can supply maddash.yaml or other config files offline if it'll help.

Sincerely,

Casey Russell
