Blue Ocean UI takes 20-30 min to load

[Andrei Gheorghiu]

Hi,

Does anyone know if this is something I can fix myself? The standard UI works fine, but Blue Ocean takes close to 30 min to load the first page - after that is loaded, browsing to others (same UI) works fine.

This didn't always happen, so perhaps there are some logs/builds I can cleanup?

I found this  bug, but it is closed: https://issues.jenkins-ci.org/browse/JENKINS-44995

Thanks,

Andrei

Check what your browser is doing while you wait. There should be specific requests taking a long time. This may be enough to file a useful bug. Provide as detailed information (HAR?) as you can.

This shouldn't happen. I have played with Jenkins on a $5 digital ocean 1GB instance and it doesn't take that long. Could it be a resource constraint? Maybe it was quick for me because I didn't have many pipelines?

Is there an easy way to replicate your experience?

Sincerely,

Hi Andrei,

We made optimization fixes on blueocean dashboard load time recently. 

Relevant PRs were for optimized favorites loading (https://github.com/jenkinsci/blueocean-plugin/pull/1638) and optimize latestRun object in pipeline response (https://github.com/jenkinsci/blueocean-plugin/pull/1635). 

These fixes went in 1.5.0-beta-1. I recommend trying latest 1.5.0-beta-2.

If it doesn't fix your loading problem, please open an issue on blueocean-plugin and attach HAR file to help debug whats going on.

Hi Vivek,

Thank you for the update.

We switched to the experimental branch on Jenkins plugins and installed the latest 1.5.0 beta. This fixed the issue for us.

(didn't notice initially that the fix wasn't on the stable release)

Regards,
Andrei

Fantastic, thanks for testing the beta, it was really a hard one to reproduce to great to have this confirmed.

Actually, we've been struggling with this issue ever since Blue Ocean 1.0, but on different Jenkins server instances (even though this last time was the worst regarding load times).

With this beta version, Blue Ocean feels speedy enough to start being our main interface.
