Brian Saville Steffen Seckler Sunil Babu Oz Tiram - tracking general slowness here.
I am having trouble making sense of the support bundles just now ("slow requests" aren't showing up in them"). If you are able to experiment then disabling the blue ocean JIRA plugin (new since 1.3) may make sense (although if you saw this with 1.2 - then disregard).
Also if you could turn on "slow requests" as an option when you generate the support bundle, would be helpful.
Vivek Pandey Ivan Meredith I am seeing some stack traces like this in the support bundles (perhaps we can get one from jenkins.io to see it at a bigger scale too):
"Handling GET /mardyn/blue/rest/organizations/jenkins/pipelines/PIPE_NAME/runs/ from 0:0:0:0:0:0:0:1 : qtp997608398-19" id=19 (0x13) state=RUNNABLE cpu=92%
at java.io.UnixFileSystem.getBooleanAttributes0(Native Method)
which implies it is our friend calcChangeSet hurting things again - this is non multi branch so isn't the multibranch activity calculation but just listing a page of runs (ci.jenkins.io DOES use multibranch on the core jenkins project, and is very slow, but may be same thing... if we can get s support core from them too may see that). More investigation needed...
