Drupal 8: A View into Performance

Views is one of the most installed Drupal modules with over two thirds of Drupal sites reporting that they have it installed. Soon, though, that number will go up: as of Drupal 8, Views is a core module! This effort started as a community effort and was announced as an official Drupal 8 initiative in a post by Dries explaining why this change is so exciting.

One of the reasons that Views is so popular is that it provides an ‘all-in-one’ answer without writing a single line of code. But there’s a reason that many programmers hate WYSIWYG editors: you see the result, but not the steps taken to produce it, and what you don’t know might come back to bite you. While a WYSIWYG editor will get you broken links or weird formatting, WYSIWYG data retrieval can have direct performance implications. A’straightforward’ View might fetch data in unexpected ways, and even ‘small’ changes like adding a node relationship can result in radically different queries. Worse, any scalability issues may only manifest when a View is run against production-like data. A View focusing on user content might start choking on a user who favorites hundreds of nodes instead of the five you tested with.
