Core Web Vitals & PageSpeed Booster vs SQLite Object Cache

Core Web Vitals (CWV) is the new ranking factor Google announced that “Core Web Vitals” are going to be a significant ranking signal for websites. In fact, Core Web Vitals or the page experience signal is going to become a requirement for a page to appear in Google’s Top Stories. Features Flush Cache: Using this option you can choose on which events ( WordPress Update,Switching Theme,Post/Page Deletion ) you want to clear website cache. Auto Clear Cache: Clear you website on regular intervals , this helps you to keep your website cache updated. Webp images: If images are slowing down your website, then converting them to WebP format can improve your page load speed test scores. Lazy Load: Lazy loading allows your website to only load images when a user scrolls down to a specific image, which reduces website load time and improves website performance. Minification: If you are trying to achieve 100/100 score on Google Pagespeed or GTMetrix tool, then minifying CSS and JavaScript will significantly improve your score. Remove Unused CSS:Unused CSS is any CSS code added by your WordPress theme or plugins that you don’t really need. Removing this CSS code improves WordPress performance and user experience. Google Fonts Optimizations: You may start noticing external resources like fonts affecting Google PageSpeed + load times. This is where loading Google Fonts locally comes into play. Delay JavaScript Execution:You can delay JavaScript based on user interaction. This can be a great way to speed up the paint of the page for Google PageSpeed when something isn’t needed right away. Especially heavy third-party scripts like Google Adsense, Google Analytics etc. Cache: Caching is one of the most important and easiest ways to speed up WordPress! it reduces the amount of work required to generate a page view. As a result, your web pages load much faster, directly from cache. Support We try our best to provide support on WordPress.org forums.

A persistent object cache helps your site perform well. This one uses the widely available SQLite3 extension, and optionally the igbinary and APCu extensions to php. Many hosting services offer those extensions, and they are easy to install on a server you control. What is this about? It’s about making your site’s web server perform better. An object cache does that by reducing the workload on your MariaDB or MySQL database. This is not a page cache; these persistent objects go into a different kind of cache. These objects aren’t chunks of web pages ready for people to view in their browsers, they are data objects for use by the WordPress software. Caches are ubiquitous in computing, and WordPress has its own caching subsystem. Caches contain short-term copies of the results of expensive database lookups or computations, and allow software to use the copy rather than repeating the expensive operation. This plugin (like other object-caching plugins) extends WordPress’s caching subsystem to save those short-term copies from page view to page view. WordPress’s cache happens to be a memoization cache. Without a persistent object cache, every WordPress page view must use your MariaDB or MySQL database server to retrieve everything about your site. When a user requests a page, WordPress starts from scratch and loads everything it needs from your database server. Only then can it deliver content to your user. With a persistent object cache, WordPress immediately loads much of the information it needs. This lightens the load on your database server and delivers content to your users faster. Who should use this? If your site runs on a single web server machine, and that server provides the SQLite3 and igbinary extensions to php, this plugin will almost certainly make your site work faster. And if that server provides the APCu extension, this plugin uses it too. Some hosting providers offer redis cache servers. If your provider offers redis, it may be a good choice. You can use it via the Redis Object Cache plugin. Sites using redis have one SQL database and another non-SQL storage server: redis. Other hosting providers offer memcached, which has the Memcached Object Cache plugin. And some large multipurpose cache plugins, such as the LiteSpeed Cache, also offer object caching based on one of those cache server software packages. The cache-server approach to object caching comes into its own when you have multiple load-balanced web server machines handling your site. SQLite doesn’t work correctly in a multiple-web-server environment. But, for single-server site configurations, SQLite, possibly assisted by APCu, performs well. And the vast majority of sites are single-server. APCu APCu is an in-memory storage medium. It lets php programs, like WordPress, store data in shared memory so it’s very fast to retrieve when needed. If APCu is available on your host server, you can configure this plugin to use it. It reduces the typical cache lookup time to one-fifth or less of the SQLite lookup time, which is itself a few tens of microseconds. Performance counts, especially on busy web sites. Please look at Installation to learn how to configure this plugin to use APCu. The plugin works fast without it, and faster with it. WP-CLI: Even if APCu is in use, caching with SQLite is necessary when your web site uses WP-CLI, because WP-CLI programs do not have access to the APCu cache. This plugin writes all cached data both to APCu and to SQLite and makes sure the two are synchronized. WP-CLI You can control this plugin via WP-CLI once you activate it. Please type this command into your shell for details. wp help sqlite-object-cache Credits Thanks to Till Krüss. His Redis Object Cache plugin serves as a model for this one. And thanks to Ari Stathopoulos and Jonny Harris for reviewing this. Props to Matt Jones for finding and fixing a bug that appeared on a heavily loaded system. Thanks to Massimo Villa for testing help, and to nickchomey for a comprehensive code review. All defects are, of course, entirely the author’s responsibility. And thanks to Jetbrains for the use of their software development tools, especially PhpStorm. It’s hard to imagine how a plugin like this one could be developed without PhpStorm’s tools for exploring epic code bases like WordPress’s.
