We should check how much time is spent parsing for Wikipedia on mobile! First let us go through a couple of extra interesting slides.
Wikipedia against the world
Marja had this slide comparing how much time is spent parsing on top site, and we can see that Wikipedia spend more time in parsing JS than maps.google.co.jp. Not sure though if that is really our mobile version or desktop. We should do our own benchmarking (we don't do that at all today). It would be really interesting to benchmark both mobile and desktop against other sites.
The amount of JavasScript that is shipped is interesting because the browser needs to spend time parsing. And remember, it is not the compressed size that matters, it is the uncompressed size.
Marja had a summary how to make things faster: "Ship less code".
Size on desktop
Size on mobile
Let us discuss this in our meeting in the performance team on Wednesday and see what can be our next steps.
