What Operating System are you using (both controller, and any agents involved in the problem)?

Host is MacBook M2 Max w/ 32G RAM. Docker Desktop. Latest LTS image (see above). macOS Sonoma 14.2.1. No agents.

Reproduction steps

Install Dark Theme with the existing plugins, reboot, page load performance drops dramatically.

Expected Results

Normal navigation performance.

Actual Results

60+ seconds, sometimes 120+, to load a page. Navigating through Jenkins is really just unusable.

Anything else?

I did start up a fresh Jenkins instance with no data and it's running beautifully. Fast and smooth. I added Dark Theme plugin and it still was smooth. It appears that this is a conflict perhaps with some other plugin.

Also, on my sandbox system I tried disabling just the Dark Theme plugin, leaving the Theme Manager plugin enabled, and the performance was normal/good.

Are you interested in contributing a fix?

I will continue testing, as I can, by disabling individual plugins to see if I can find the conflicting plugin(s).

I'd be surprised if dark theme is doing very much. All it does is add an endpoint for a CSS file

I agree, but I flip that switch (enable/disable) with the current plugins in my list and page loading is garbage or great. Must be one of my other plugins that doesn't like dark theme. Not sure which yet.

https://plugins.jenkins.io/monitoring might help you find out which plugin is causing this

Thank you @zbynek

hello @kerrhome did you find the reason why this happens ? I have similarly problem, I have 5 jenkins instances and only one with dark theme has this problem.

I also have the same issue. Requests to /theme-dark/theme.css time out eventually, but it kills the UX loading experience.

When the real jenkins url in browser is mismatch with configured Jenkins URL , there maybe some load problem in /theme-dark/theme.css file.
Request url was generated based on configuration, not the real url in browser.

@cuiliang that sounds like a wrong revere proxy setting, the Jenkins URL should match the real URL in browser.

@zbynek I am moving jenkins to another server using backup-restore method, when still not have proxy setup, access jenkins using http://localhost:8080, will have this problem.
I dont know if it is possible to generate theme.css url using request information, if can, will solve this problem.
