In reply to a post by jaydub:

There are a number of us that have reported this wavy sawtooth effect (it is different from the sawtooth in your FAQ). I am using the same Netgear Orbi router as I was on FTTC where the minimum latency line was flat. The only difference I am aware of is that IDNET had me on BTw backhaul on FTTC and my FTTP is a ZenW connection via OR.

This is mine for reference.

Hmmm.. it does seem a bit odd to have this vary by line type. I would be surprised of an ISP level network was traffic shaping anything.. I presume CGNAT is not a possibility here.
I am quite curious about this pattern though.. would like to track it down.

Hi Seb,

I'm on a fixed IP address. I am one of several that have reported this on moving from FTTC to FTTP

See an example here: https://forums.thinkbroadband.com/bqm/t/4731628-re-p...

My F8lure stats are a flat line for the minimum latency, so my gut feel is that it seems to be something specific to the way the TBB monitoring is configured.

As earlier, it is there on mine. BT Business, IPv6 & v4 although "teeth" reversed:

This makes it more likely to the CPE related.

My new FTTP 330/50 with AAISP has this sawtooth effect on the BQM too:
