“Content Download” extremely slow in Chrome, not in Incognito or other browsers

I have a logout endpoint that takes several seconds to resolve in Chrome (sometimes up to 30 seconds in production), but only around a hundred milliseconds in every other browsers (Firefox, Safari...) and in a new Chrome Incognito window.
Firing the request locally from Chrome against the staging database also runs smoothly.
Checking the Timing tab in Network shows that timing for Request sent and Waiting are normal, but Content Download is where most of the time is spent.
I have tried turning off all my extensions (and rebooted Chrome) and tried browsing the Chromium bugs board, to no avail:
- slow content download
- Network panel shows huge Content Download time for 304 response
- Slow Content Download on Chrome
Here's the request:
curl "https://XXX.XXX.com/deconnexion"
-H 'Authority: XXX.XXX.fr'
-H 'Pragma: no-cache'
-H 'Cache-Control: no-cache'
-H 'Upgrade-Insecure-Requests: 1'
-H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36'

-H 'Cookie: __cfduid=XXX; cookie_consent=true;'
Which returns an empty response with the following Headers:
