As a developer I'd like to have small HTML report size in order to reduce disk space consumption, especially in case of builds on CI server.

Possible ways to reduce report size:

1) extract list of packages to separate JSON file and load it dynamically using JS function (instead of embedding it on virtually every page) DONE

2) use some html compression utility (which would strip all whitespace etc)

performance of the HtmlCompressor is unacceptable (+340% time)

3) remove whitespace from most frequent loops from velocity templates DONE
