Network speed degrades instantly, not gradually. Long time since boot seems not required to trigger issue.

At least for me the problem seems to replicate with iperf on localhost as observed in #18203.

Duplicate of #12876 maybe?
IIRC, this was briefly investigated by a developer (cannot remember who) and determined that the problem is likely in the TCP stack related to scaling of some sort.
