SQLite Object Cache vs Flash Cache

Flash Cache is a powerful plugin which optimizes the websites speed thanks to processes and technologies that reduces the overload of the websites where it is installed, improving the velocity till 10x comparing with other cache plugins for WordPress. With the Flash Cache plugin you will be able to: Increase the speed at which your site is displayed to the end user. Reduce the use of server resources when there are many visitors. Create a more enjoyable experience for the user. Help with the positioning and the SEO of the web site. Decrease the workload on the system behind the cache. And if that’s not enough for you, read on for many more benefits. Some Features The most important characteristics that makes this add-on the first choice comparing to others are the next ones: The Flash Cache plugin is tested with the most important servers that can run WordPress, such as Apache, nginx and LiteSpeed and supports PHP 5.6 to 8.2. Flash Cache allows infinities configurations thanks to the patterns, these can be done with different cache patterns according the kind of page that will be cached. It avoid the PHP execution in foreground at time of serve the cache objects, improving significantly the performance and the overload of the server. Crawl Budget optimization, the majority of the search engines assigns a quantity of means to go over the websites, with Flash Cache a higher number of pages are indexes and is better positioned in the search engines. It allows keep the content in the cache updating instantaneously when is modified, for example, when a new post is added, it creates a cache object of the post and it can refresh other pages automatically as the homepage. In addition to optimizing the cache on the server, it manages the cache in the web browser improving the performance in client-side and server-side. It allows to make a preload of the entire website, to keep a cache of all the site optimized and configurable. Most of the cache plugins in WordPress break the website structure, and this brings problems at the time of move the websites to another hosting or domain. This problem doesn’t exist with Flash Cache. You only need to deactivate the cache and the plugin you can change the hosting of the website and reinstalled the Flash Cache without problems. Known third-party plugins or theme compatibility issues In some cases, there are compatibility issues with other plugins. Most of the time this is caused by other plugins inserting javascript or styles in a wrong or weird way. Shortcodes Ultimate: Uncaught ReferenceError: SUShortcodesL10n is not defined.

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.

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.
