WordPress is a great content management system to start with. But there are things you can do to improve its performance. You can optimize your images, invest in a decent CDN service, and more. The WP Performance Pack can also help make your website more responsive. It performs various WordPress optimizations without the need for you to patch core files.
WP Performance Pack is designed to improve the performance of translated WordPress installations. It loads translation files dynamically. You can use native gettext if available. Users have the option to disable backend translation. Debug Bug integration is available just in case you want to monitor your site more closely. Caching of translations can further improve the performance of your website.
WP Performance Pack can’t do miracles but it can help improve the performance of your translated site slightly. It is a free plugin.
