Hi,
I think I know the cause here as I reviewed the change likely causing this (I thought it
wouldn't have a measurable performance impact as Sites are being loaded anyway...
Seems I was wrong there).
I will have another look at this soon and try to cache things on another layer so that we
don't have to pull Sites that often.
Thank you for bringing this up.
Cheers,
Marius

In November of last year, Aaron noticed a spike in
memcached traffic,
which
we were eventually able to attribute to Wikibase client fetching the
SiteList on every request. When Katie fixed it, outbound memcached
traffic
nearly halved.
We're now back to the same rate of outbound traffic as then, and the
culprit appears to be the same key.
