The stack has reached a new peak.

With 556 active contributors per month, this quarter is the highest in the history of OpenStack. Compared to the previous quarter, core and regular contributors have also increased 10 percent and 20 percent, respectively.

That extra buzz of activity hasn’t slowed the work down, either. The mean time for a reviewer to

comment on a patchset used to stretch over seven days, but in this quarter that turnaround time is down to five days. Also for the first time, contributors submitting changesets seem to be reacting faster to comments from reviewers and submitting new patches faster. That trend doesn’t extend to Nova and Glance, which still have very high time-to-merge, meriting a look into the reasons why.

The report also tracks hot community topics, including the most active discussions on the mailing list, which remains the busiest channel. In this quarter, they included discussions of the six-month release cycle and follow-up discussions from the Mid-Cycle Operators meetup.

Those are the main highlights from the latest OpenStack Community Activity Report, which covers January-March 2015. Daniel Izquierdo Cortázar, chief data officer at Bitergia, and Stefano Maffulli, OpenStack developer advocate, crunched the numbers for the quarterly report.

The quantitative and qualitative assessment tracks actions across all OpenStack Git repositories, Gerrit code reviews, bug trackers as well as IRC channels, mailing lists and the question/answer site Ask OpenStack.
