Hey, In general, the performance implications of an edit for fixing redirects heavily outweighs the small improvement of removing a redirect.
The biggest exception to that is main pages of wikis (which redirecting en.wikipedia.org to en.wikipedia.org/wiki/Main_page actually wastes 27 years of Wikipedia readers time every month) [1] so if there is lots of clicks coming for an article from another article (you can find those in clickstream datasets [2]) this might be a good idea to fix but in general I don't think so and it's even more work for the system to re-render the page, update links table, etc. [1] https://phabricator.wikimedia.org/T120085 [2] https://dumps.wikimedia.org/other/clickstream/ On Mon, Dec 28, 2020 at 3:06 AM Thibaut Payet <[email protected]> wrote: > Thank you very much for your detailed reply. > > We tried to convince our friend with your message and WP:PERF but he's > still not convinced, he even created a RfC on frwiki which is currently > being discussed[1] and we need some more information. > > He created these two pages: > * <https://fr.wikipedia.org/?oldid=177832893&uselang=en> (list of > redirections) > * <https://fr.wikipedia.org/?oldid=177847552&uselang=en> (list of direct > links) > > Previewed them and argue that the parser profiling data table shown > below the page indicate that there's less CPU time/real time usage with > the page using direct links than the one using redirects: > "As surprising as it may seem, the page that gives the best result is > the one with the direct links.
