Summary: Ref T7708. This changes things to $viewer->loadHandles where applicable in the durable column render stack. I saw some big wins on my test data like 34 queries => 24 queries on a newly created room as my default thread. For my test data, the next big perf win would be to change how remarkup rendering works and try to multiload all objects of a certain type in one shot. e.g. `PhabricatorEmbedFileRemarkupRule` implements `loadObjects` as do all classes which inherit from `PhabricatorObjectRemarkupRule`. This is because `PhabricatorObjectRemarkupRule` implements its `didMarkupText` method using `loadObjects`, and `didMarkupText` gets called per transaction over in `PhabricatorMarkupEngine->process()`. Instead, the `loadObjects` in `didMarkupText` should be hitting some cache, and we should do a bulk load for all `PhabricatorEmbedFileRemarkupRule` that had matches earlier in the rendering stack. ...I think. Test Plan: carefully looked at "Services" tab in dark console and noted fewer queries with changes post changes versus pre changes Reviewers: epriestley Reviewed By: epriestley Subscribers: Korvin, epriestley Maniphest Tasks: T7708 Differential Revision: https://secure.phabricator.com/D12780 |
