Thanks Tom,
Yeah my test points VM's where all FreeBSD 10.3/11.0, so I decided
to randomize some of them and added a CentOS on my Telia peer (10Gbps),
and start getting normal performance from GCLD ( In the 500Mbps/500Mbps
range )
PS: Even weirderer(tm) The *BSD VMs always performed correctly in
the past, but not for this particular case.
I have some work left to normalizing those peers, the same tactic
didn't work on the other ones.
if anyone have some lead on a TCP stream analyzer that would cut
down on the number of naps I need to take looking for clues in wireshark
captures.
