Jenkins 2.7.1, Jacoco-plugin 2.2.0
If a Jenkins job has a very large code coverage report (say 10,000+ class/source files) it causes the build page in the UI to load very slowly when using the jacoco code coverage plugin. I believe this is because the entire report is being read into memory before the page can load.
The build page only loads an overall coverage summary with 6 pieces of data. If this summary was instead saved/cached on the filesystem and used for this page the entire report would not have to be loaded.
The coverage report would obviously have to be loaded if the user goes into the coverage report UI but that is unpreventable. If however the user is looking up information about the build and does not desire full details of code coverage there is no reason the whole report needs to be read into memory.
