PHP 7 at Tumblr

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

Tumblr が PHP7 へ移行。 Phan を使い静的解析を行いつつ、 CI では PHP5 系と 7 系の二系統を回しながら作業。移行により latency, load average 共に大幅に改善

PHP 7はPHP 5 と比べると実行速度が大体2倍速くなる。PHP 7に準拠したコードを書いたらもっとパフォーマンスが良くなるのかなぁ。
