  • After updating to 4.2.1, the WordPress editor has become unbearably slow, typing a few characters takes a few seconds to catch up (on a page about 20K characters).

    I have an Intel Core i7, 16 GB of RAM, run Linux 64 bit and Chrome stable version 42.

    While typing, Chrome’s CPU use shows in htop around 100% – 180% (> 100% means multiple CPU cores).

    Using Chrome Developer Tools, I collected a JavaScript profile. The time is consumed in wp-emoji-release.min.js?version=4.2.1 and the hot path there is:

    e > i > d > h.observeChildList

    I really hope this serious front-end performance problem can be fixed, and also hope that emoji support becomes optional with a setting in WP itself, not plugin.

    Hello,

    I’m also having trouble with “Flush All” (in the admin console, as a test).

    I can see the AJAX request is getting executed, but the cache directory still has all the files.

    Do I need to install anything on the nginx side to enable cache flushing?
