After installing css_editor module on my local ddev environment, saving the theme settings took 40-80 sec. (compared to ca. 10 sec. before installation and with loading the settings page without saving ca. 5 sec.).
Tested with css_editor module versions 8.x-1.0, 8.x-1.2 and 8.x-1.x-dev.
Environment:
* Drupal 8.8.5
* Apache/2.4.38 (Debian) running on ddev v1.14.1 on Windows 10
* PHP 7.3.16
* Database 5.5.5-10.2.31-MariaDB-1:10.2.31+maria~bionic-log
* Themes: Custom theme based on drupalexp_lite, with color module activated
