PHP 7 at Tumblr
Another big boy on the web upgraded to PHP 7. If you're not yet on the train heading for PHP7-ville, best get your ticket soon, you won't regret it.
At Tumblr, we’re always looking for new ways to improve the performance of the site. This means things like adding caching to heavily used codepaths, testing out new CDN configurations, or upgrading underlying software. Recently, in a cross-team effort, we upgraded our full web server fleet from PHP 5 to PHP 7. The whole upgrade was a fun project with some very cool results, so we wanted to share it with you.
