I actually disagree — GitHub has been relatively slow for me when it comes to page transitions. For example, switching between a PR’s various tabs would probably be a lot faster with client rendering.

Of course, performance will come down to how well the team builds the site and optimizes it. It is very easy to make a site slow in so many different ways. You always have to be looking at and optimizing it for improvements, both on the client and server. React isn’t immune to this, just as various server frameworks aren’t immune to it either.

Agreed. I'm rather surprised at people in this thread saying they prefer GitHub's server rendered setup. I use GitHub a lot in my job and it feels rather slow/clunky.

All the people that were used to Bitbucket’s 20s page loads think Github is heaven.

I'm curious what relatively slow means for you.

As an example I just made a quick test from my Firefox mobile browser in desktop mode and the switch between PR tabs is not instant but close enough to not be bothered by it.
