Since anything I write would be incomplete without your description of what
caused it and how you resolved it, I put together a WIP write up here, with
screenshots / link to logs*. Feel free to use it as you want or let me know
if you'd like more details; I'm happy to help write the complete story for
a page on
which is probably the most reasonable place to gather the relevant bits.


* I rerun the tests to capture timeline screenshots, so the server-logs
don't exactly correspond to those screenshots, but the behaviors were the
* Note that the delays in the timeline pictures are worse than those seen
on server logs, which have been more helpful for understanding
application-layer behavior. I think what's causing this is a bloated output
buffer in the case where the server aggressively writes low-prio data
(verified this by monitoring the buffer size which keeps increasing during
the test)
