Does that run RouterOS 7.2?

I am not in a position to "recommend" anything, but I am very
interested in the current bufferbloat'd behaviors of
VDSL2 and FTTH on what you currently have deployed, and what you plan to deploy.

At a gigE, I am getting back behaviors worldwide that range from
seriously underbuffered (5ms), to unable to transmit Gbit
simultaneously in each direction without the router running out of CPU
(very common), to 30-90ms. On various shapers, at 200Mbit, I'm seeing
20ms-200ms. and the lower values can really hurt single flow
throughput.

So I've been trying to get folk do tests worldwide with the rtt_fair
test in flent.org There's a server in sydney. Here's an example of the
otherwise rather nice turris falling apart at 200Mbit symmetric:

If you go the mikrotik way, I'm happy to say they finally made "cake"
work pretty good in the 7.2 release, which,
so long as you don't run it out of cpu, essentially is doing zero
latency for most packets while having enough buffering to sustain
cubic at 260ms rtt. A very long thread with a ton of explanations and
pictures here:

There are a ton of other branch office quality gear that run "my"
stuff now, also, ubnt, riverbed, etc, etc. I figure y'all have way
more technical requirements that just killing off bufferbloat,
however!
