I am curious as to the drop and mark statistics for those actively

but NOT obsessively testing dslreports' speedtest as I have been :),
over the course of days.

A cron job running once an hour would work, but snmp polling with
mrtg, parsing the tc output would be better.

But a quick survey would be interesting, if you could dump your

uptime
tc -s qdisc show dev whatever
tc -s qdisc show dev your_inbound_ifb_device

here?

and also check to see if you are getting drops or marks on your core
wifi interfaces. For example a great deal of the dropping behavior for
me has moved to wifi over the last year (as we upgraded from 20mbit
down to 60 or 110mbit down), particularly on my longer distance links
but also on links that have very good same room connectivity.

example wifi interface (6 days of traffic)

this is the same routers external interface (60mbit downlink) (yes, I
