--- Comment #18 from Mark Thomas <> ---
I've made a couple of changes in light of my research.

1. I have added some code to ensure that, if a larger than default initial
window size is configured, then Tomcat will follow the initial SETTINGS frame
(typically in the same TCP packet) with a WINDOW_UPDATE frame to increase the
size of the flow control window for the connection.

2. I have switched to using the average size of the current and previous DATA
and WINDOW_UPDATE frames to test against their respective thresholds. This
allows some smaller frames (e.g. those caused by the buggering behaviour seen
here) when surrounded by larger frames but will still close the connection
quickly if lots of small frames are used.

These changes will are in:
- master for 9.0.25 onwards
- 8.5.x for 8.5.46 onwards

I'm still hopeful that Chrome will make some changes to reduce the number of
small, non-final DATA frames it sends during an upload.
