We recently upgraded our Jenkins CI servers to the latest LTS version
(4.480.1 -- before this we were using version 4.447.2) After this upgrade,
we found that on our busiest servers (especially on a master of 8 slaves;
all run on Windows Server 2008 r2) that the http response becomes very
slow. It's inconsistent, but approximately half of the time the GUI
responds either sluggishly or seems stuck. Has anyone experienced this?
Does anyone have suggestions for how we can investigate the cause of this?
We thought it might be due to intensive SCM polling activity of many
projects' commit jobs, so we increased the polling intervals and spread
them out more, and this had no effect. I'd appreciate any ideas. A small
related question: one of the things we want to do for our investigation is
to record logs of http activity. Which logger name(s) should we use to
capture such logs?
