go626201I'm starting to suspect it is your upstream problem. Either to your BNG (2001:e68:402c:8001::77)
OR
MPLS circuit in between (2001:e68::b:42)
Instead of pinging all the way to Google, can you bi-sect it by pinging your BNG first? If it still happen then it is between you and the BNG.
Next test the MPLS circuit by pinging 2001:e68::b:42.
Also, can you just check your CPU are not bottlenecking? Go to Tools > Profile and monitor it.
Are you running container on your router? Can you stop them if you do?
EDIT:
We will deal with the IPv4 problem later. I suspect that one is due to MPLS circuit too but it is very difficult to test them as an outsider. If you can get me some traceroute to:
Group 1. Affected servers
Group 2: Not affected servers
Then I might be able to come out with a guess which place to ping.
blacktubiCan you describe what problem is cake having? I just want to get a mental model to understand if it is related to his current problem.
Hi Thanks for helping me to find out the issue.
I tried to speedtest and uploading again,and pinging to the hop at the same time.
Both Google and second hop showing the similar spikes at the time i uploading.


The 2001:e68::b:42 is not replying ICMP. So cant get the result.
CPU no bottleneck, i never have my RB5009 at 100% usage before.
No container running.
Affected servers currently not sure. As far i test,i found out as long as i am uploading,the latency will spike whether i using full speed or not. (Especially uploading more than 200+mbps)
Edited:
As for the cake queue,i not sure currently is the issue affecting the speed or not or the cake really buggy that this morning i test can only get 200+mbps upload. (This might need a retest after the issue fix)
So far i am agree about your suspicion on the BNG.
(Actually i was facing similar issue with torrenting-low torrent speed also occurs before FSU,but at that time i using Queue was due to the bufferbloat on download side,but now download didn't have bufferbloat issue anymore,and this upload issue came after FSU,and i think it only occurs after hitting more than 200mbps on upload side)
