--- Comment #4 from Antoine "hashar" Musso <[email protected]> ---
This got fixed for now after a looong night of tweaking.

The API calls were hitting the full console log which is definitely slow. That
one got fixed by Ori and merged upstream.
https://review.openstack.org/#/c/28128/

The Jenkins API call was hitting an URL that triggered a full parse of the
build history for that jobs. The workaround as a live hack was to let Zuul
pretend the job always exist. https://gerrit.wikimedia.org/r/#/c/62095/

Two threads in Jenkins were waiting for each other (as I understand it) causing
overall slowness. That got resolved after yet another restart.


For now it seems to be stable. We will see how bad it is after a restart and a
slow start, maybe something to try out in the morning.

Lowering priority for now.
