Brion-
I've temporarily disabled talk page notification
for IP addresses that
aren't logged in, as this dumps an extra database query for every single
hit.
If it doesn't make a big difference, it'll get
turned back on shortly.
Hmz, how do we measure "big difference"? Wikipedia has been everything
from "dog slow" to "super fast" since this announcement, but
that's about
the usual. I don't believe one SELECT to a small table on each pageview
matters much, but then again, I still don't understand all the locking
issues which we seem to have. Remember the orders-of-magnitude increase in
speed after we switched the searchindex to a static copy? Yet I don't
really see why it ended up being locked so much.
Presently I see locking issues and very slow rendering of long pages (IMHO
still caused by the link checking process, but I haven't validated that
theory) as the two main causes of our dismal performance (that, and the
fact that people like us too damn much). I had hoped that Tim's links
update fix would make a big difference, but it turns out that saving long
pages is still slow because they are also *displayed* after saving them,
and it's the displaying itself that is slow. I don't really know how much
of an impact the current 2394^34 pass parser has on the performance on
Larousse, but I wouldn't rule that out as a cause of headaches either.

Erik
