Hello,
In the second half of January 2017, the version of Node running in WMF
production has been updated from v4 to v6~[1]. Parsoid, RESTBase, AQS and
the services running on the SCB cluster (Graphoid, Mathoid, Mobile Content
Service, to mention just a few) are now running on Node v6. The only
outstanding Node service which is still running Node v4 is Maps, but we are
making good progress on moving it to Node v6 and expect it to happen
soon~[2].
In the case of services running in WMF production, we have seen a slight
increase in performance as well as a substantial decrease in memory
consumption across the board, which improves the stability of our services.
You can read more about the experience of the update and its results in the
post published on Wikimedia's blog~[3].
Big thanks to all of the people that helped to make it happen!
Happy Friday,
Marko && the Services Team
