Hrm... I should probably go ask them about that.
But I'm curious about
your perspective and to see if we have any information on the bandwidth
available to various users.
There is some, but not enough for us to know in advance what sort of
impact this will have. But Aaron Hafaker and I are working on it, and
we are going to be rigorous about measuring it, and we will report
We ran a controlled test and found that module storage reduced page load
times by 156 ms, on average. Aaron has some data available at <
we still need to write several sections. The size of the effect is
substantially smaller on mobile, for some reason, which is surprising. We
hope to make the dataset public soon.
156ms shaved off of 90% of page views is pretty nice.
reading for context and scale:
"This conclusion may be surprising -- people notice a half second delay? --
but we had a similar experience at Amazon.com
. In A/B tests, we tried
delaying the page in increments of 100 milliseconds and found that even
very small delays would result in substantial and costly drops in revenue."
We'll gradually enable module storage on all Wikimedia wikis over the
course of the next week or two.
