Jenkins v2.89.4 w/ workflow-job-plugin v2.25
Jenkins v2.150.3 w/ workflow-job-plugin v2.31
Jenkins v2.289.2 w/ workflow-job-plugin v2.41
We recently upgraded Jenkins from 2.89.4 to 2.150.3 and then upgraded the workflow-job plugin from 2.25 to 2.31 and are now seeing an issue where the full console log in the Jenkins UI is having issues loading. We run a parallel pipeline heavy workload which results in a 13mb console log in 2.150.3 and a 46mb console log in 2.89.4. In Jenkins 2.89.4, it took 45 seconds to load the full console log file in Chrome and even less time in Firefox. In Jenkins 2.150.3 the log file took 2m 30sec in Chrome and after 5 minutes never loaded in Firefox. I kept seeing "A web page is slowing down your browser. What would you like to do? [Stop It, Wait]" and eventually Firefox became unresponsive. I used Chrome 72 and Firefox 65 in my testing.

I think it is because the javascript function which loops each line and appended parallel label
https://github.com/jenkinsci/workflow-job-plugin/blob/master/src/main/resources/org/jenkinsci/plugins/workflow/job/console/NewNodeConsoleNote/script.js#L21-L42
It can be reproduced by a generating lots of lines in parallel step, such as
The consoleFull is very slow and firefox complaining about the js
jglick does it make sense to generate the label in backend(Jenkins side) ?
