Reviewboard does not make it trivial to create such an integration at
this time. Please read the report where this is explained in full.
Phabricator does make it easier, please see the links i've posted to
the mailing list.

Scarlett's efforts are KDE specific and relate exclusively to Jenkins.
We would provide information to the Phabricator community on how we
achieved our integration of course.

Git runs on the physical host Kater (i7-2600 w/ 32gb RAM). It shares
this with Identity, CiviCRM and Jenkins, as well as our IRC services.
The machine isn't heavily utilised except at certain times - but that
is caused by scaling issues in the anongit network. At all other times
the machine is fairly idle.
Reviewboard runs on the physical host Tesla (i7-950 w/ 8gb RAM). It
shares this with reports.kde.org, an Owncloud instance and some other
Once again, the machine isn't heavily utilised except when someone
makes a large number of commits or sends a stack of emails, which
generates a bit of load as reports.kde.org processes them (design is
slightly suboptimal here).
Bugzilla runs on the physical host Katze (i7-3770 w/ 32gb RAM). It
shares this with the Dot, Forum, Wikis as well as all our other CMS
based sites including krita.org, calligra.org, kdevelop.org and
kdenlive.org. It also hosts todo.kde.org and paste.kde.org. This
machine gets a little busy during the EU daytime due to these other
sites - Bugzilla doesn't present a load issue (it is a memory hog due
to the Perl and MySQL caching needed to keep it performant when
queried, but is itself a very low hit rate site).
Quickgit runs on a donated container, on the anongit node Serenity. It
shares this with nothing else. There are no load issues here.
Chiliproject is extremely suboptimal, and a massive resource hog. It
runs on a separate machine again.
I don't expect there to be any issues requiring us to cluster or move
beyond one server hosting Phabricator.

What was in production? The hack allowing for reviews to be posted
using Git itself? It isn't at this time...
