Please fill in all the following sec
#### Descriptions.
= Description =//(Please provide the context of the performance review, and describe how the feature or service works at a high level technically and from a user point of view, or link to documentation describing that.)//
Please provide the context of the performance review, links to relevant documents describing the change/new feature here.#### Preview environment
= Link(s) to Beta Cluster wiki(s)//(Insert one or more links to where the feature(s) can be tested =, e.g. on Beta Cluster.)//
Hosting the changes on Beta Cluster is a requirement prior to performance review. Please ensure that the feature can be used directly on the link(s) provided, without any data entry such as having to create an article. Test article/dataAny sample content needed should be provided alreadyalready be present.
If the changes cannot be hosted on Beta Cluster, justification for an exception must be provided and the changes still need to be hosted on a wikiexplain why and provide links to an alternate public environment instead where the Performance Team can access andalso SSH into. Providing only lLinks to code only is insufficient for thea performance review to start.

It should also include what maydescribe changes which have not haveyet been merged yet,ed or deployed but are planned prior to deployment. but is planned for deployment (egE.g. production Puppet, wmf config, or in-flight work to befeatures expected to completed by deployment time prior to launch date, etc.).
=#### Performance assessment =
Please complete your owninitiate the performance assessment here.by answering the below:
- What work has been done to ensure the best performance possiblpossible performance of the feature?
- What are likely to be the weak areas of the feature(e.g. bottlenecks) of the code in terms of performance?
- Are there potential optimisations that haven't been performed yet?
- Please providelist which performance measurements ofare in place for the featureeature and/or what you've measured ad-hoc so far. If you are unsure what to measure, ask the Performance Team for advice: [[ mailto:performance-team@wikimedia.org | performance-team@wikimedia.org ]] (give us as much context as possible if you do!).
