[Staging #NGZ-668874]: RE: Requesting LDM access for FNMOC feed.

This is confusing, because I'm seeing about an 18.6 Mbit transfer rate between shu and the outside world.

Hi Samuel, 

All feeds are treated alike in the IDD/LDM world. I suspect there may be firewall issues or volume throttling occurring locally. We can offer you a feed from our machine to shu1 to verify any local issues. I would contact your network folks first to see if they can shed some light on this.


Cheers,

Jeff

Many sites use the LDM internally and have not experienced this issue.
