Details

(Keywords: meta, perf:pageload, Whiteboard: [perf:investigate])

Right now early during page load there are several ping-pongs from child to parent and back to child etc to get the child actually load a web page. And often parent process is rather busy at that point swapping frameloaders or doing some frontend work and that prevents the child process to get the data soon enough. There should be ways to get the data to the child process sooner. Problems are around having the BrowsingContext in the child process in the right state when loading starts, if that loading starts sooner.

And we seem to have also some issues where we don't really utilize parallelism as well as we could

Let's close this meta bug. We can do more in this area, like bug 1603605 and bug 1803966, but I don't think I'm going to work on them right now.
