Dan,

When you say the huge amount of data is slowing the load, are you referring
to the size of the Edit event logs? That wouldn't make sense since I
thought the data is all pre-computed and loaded from the TSVs every time
you load the page.

Anyway, as a heads-up to everyone, new data generation for that dashboard
has been disabled since those logs have gotten too big. We've already
reduced the volume of new Edit events to 20% of previous by increasing the
sampling, and the DBAs are going to randomly purge existing events (
https://phabricator.wikimedia.org/T124676). Once that's done, we can turn
the computations back on (https://phabricator.wikimedia.org/T126058).
