Re: Google Cloud and IX - Traffic behavior

Just did a quick test from a personal VM, no throughput difference over
direct peering, public IX, or transit. GCP might have a bottleneck in your
case though, might be a good idea to ask them.

Also, I'll have what Gordon is having.

   Hi,

   Yes Stephen, we're talking the usual like GTT...

   And no latency wise they're about the same.  In the 35ms range.

   But I still can't figure out the 10 x drop, that level of latency
alone cannot be the factor.

   ( And Gordy...  what?!? )

Alain,

When you refer to "normal peering" do you mean Internet transit? Or are
these PNI's with Google?  Do the GCLD instance you reach through "normal
peering" have higher latency than through TorIX?

    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
