     Hi,

     Anyone aware of different traffic behavior depending if the target 
goes through normal peering than through an exchanges google exists in?

     We're facing a weird issue where the same GCLD Instance can upload 
up to 200Mbps (Ref 1) if the target path goes through, lets say TorIX, 
but cannot get more than 20Mbps on similar hosts (8 of them) sittings on 
our peering links.

     PS; Those sames hosts get up to their link limit ( 1Gbps ) between 
each others and others test points we have;

     PS: Wireshark capture show nothing abnormal;

     PS: Links aren't congested, and so on...

Ref 1 - 200Mbps is on a link rate-limited to 300Mbps.  Its my only test 
point with a TorIX access
