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
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.

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. Exactly the opposite of those who want to
prohibit the fixes [note: we don't], it is precisely the direct links
that give the best results. Go figure."[2]
Does that kind of benchmark makes sense? Is the parser profiler data
even relevant here? What exactly is calculated?
Sorry for all these questions but we would be grateful if you could shed
some light on this.
Happy holidays,
Thibaut Payet

While the specifics may have changed over time,
the general point of
the page is correct -- "fixing" a redirect will use significantly more
server time than clicking on one. When you click a redirect, MediaWiki
queries the redirect table to see where you should go instead. Reads
from the database like this are fast. However, when you edit the page
to "fix" a redirect, MediaWiki has to save the edit, update the links
tables, re-render the HTML, invalidate the cache, and serve the new
HTML, among other things.
From a reader's perspective, there's no performance difference between
clicking a redirect and clicking any other internal link. We're
talking milliseconds here, if that. If you wanted to really improve
the performance of a page, remove all the images. (Note: do not do
this.)
This falls under
<https://en.wikipedia.org/wiki/Wikipedia:Don%27t_worry_about_performance
:
let the developers and the operations folk worry about performance. If
you're already making an edit to an article and you feel like
bypassing a few redirects, go ahead and knock yourself out. But going
out of your way to "fix" links to redirects is just a waste of your
time.
