The job queue was at 97K.
Fragment of a discussion from User talk:Rua
That's really all I did. Ruakh reverted it though and then I re-did it in a way he wouldn't disagree. So that might have done it. Why, is the long job queue causing slowdowns?
AFAICT the point of the job queue is that it keeps changes from causing slowdowns, so I don't think there's a problem with it being large for a day. Its length also doesn't seem completely predictable; I've changed widely used templates once or twice and only noted a queue of about a thousand afterward, which quickly dissipated. Weiter so.
