Naming and scope

I am proposing adjusting the name and scope of the team.


  • Extend the charter of the Performance team to Performance and Availability, with a focus on site scalability, availability and performance of Wikimedia sites.

What this expanded team will do

  • Identify and correct significant risks to the availability and performance of the Wikimedia sites, either by itself or in co-operation with other teams.

What this team will not do

  • Initiate product-related improvements to the MediaWiki platform
  • Support third-party use of MediaWiki (with technical support, improved packaging, etc.)

Core metrics

  • Site performance, particularly time to first paint and time to save an edit
  • Uptime


The Performance team is already a de facto Performance and Availability team. Recent projects have included:

  • fixing the backlogged job queue;
  • diagnosing HHVM-related memory leaks;
  • contributing etcd support to PyBal, the load balancer;
  • automating legacy code deprecation in MediaWiki;
  • writing Puppet modules for Apache, Redis, and HHVM
  • instrumenting MediaWiki internals and creating dashboards for key metrics

Ongoing projects include: - revamping and modernizing the image rendering stack; and - readying MediaWiki’s codebase for multi-datacenter deployment.

The existing Performance team contributes non-performance related features that enhance the availability and scalability of Wikimedia sites. Implementing this proposal would formalize a slightly expanded scope and raise the visibility of the team inside and outside of the Wikimedia Foundation. It will demonstrate the Foundation's dedication and focus to a core task: keeping Wikipedia and her sister sites up and running to the community.

Financial impact

Implementing this proposal would formalize the scope of an existing team without any headcount additions.

I invite comments and feedback about this proposal. --Ori Livneh (talk) 01:11, 9 March 2016 (UTC)
