I am curious about some of the speed aspects in 4.2 in relation to Bootstrap 5. Having read various articles like the one below, my understanding was that combing CSS and JS is actually counterproductive when using servers running http/2 or later and was essentially a “best practice” idea to work around limitations of older servers.
Going back a few years ago with Rapidweaver I found that sites ran visibly slower in real world testing and it tended to break things when I enabled this option, so I ignored reports from Google PageSpeed etc telling me to unify these files.
I gather that Bootstrap 5 changes the static site builder from Jekyll to Hugo, which is significantly faster, however I was just reading another article suggesting that Hugo contains a built in function to unify these files automatically and we should enable it.
Obviously there is no substitute for live testing but I am curious how this is likely to pan out in real world usage without being distracted by online speed tests that may not be up to date.
