speed. Tracking the "does this article exist" mechanism, I ended up at
the preFill function in LinkCache.php, which reads all existing links
for a page in a single query, avoiding zillions of queries later.
Now my question: Is there a reason why it doesn't pre-fill the "bad
links" array as well? That would save some time on all pages with more
than one broken link, would it not?
On the English wiki at least (where performance is critical), most links
are live. It's fairly rare to have more than one or two broken links on
a page, so a prefill on those might not save much.
On the other hand it shouldn't be much slower in the common case. If you
want to add it, feel free.
