Dessky Cache vs SQLite Object Cache

Dessky Cache is the ultralight caching plugin for WordPress that makes your site faster by generating static HTML files and stores them on the server’s disk. The web server will deliver static HTML file and avoid the resource intensive backend processes (core, plugins and database). This WordPress cache engine will improve the performance of your website. Plugin is suited for simple blog websites that are hosted on shared hosting with limited resources. This plugin was developed by Dessky Team. Dessky Team does not provide support for the Dessky Cache on the WordPress.org forums. In order to get support or make a suggestion from a Dessky Team you will have to Join Our Open Community and Start a Discussion. DISCUSS WITH THE DESSKY TEAM JOIN OUR OPEN COMMUNITY: The purpose of this open community is to have a collective place where the community can help each other, and we can get some feedback to improve Dessky Cache as well. Joining the community is also a great way to connect with like-minded people and share your experience. You can also GET THE PREMIUM SUPPORT User Documentation: Although Dessky Cache is already easy to set up, we’ve put together tutorials, guides, and some knowledge bases to help you set up and get started with it. I have further questions, how do I contact you? Please fill up the contact form and we would be more than happy to assist. Features Efficient and fast disk cache engine Automated and/or manual clearing of the cache Manually purge the cache of specific pages Display of the actual cache size in your dashboard Minification of HTML and inline JavaScript WordPress multisite support Custom Post Type support Expiry Directive Support of 304 Not Modified if the page has not modified since last cached WebP Support Supports responsive images via srcset since WP 4.4 HTTP/2 Focused Dessky Cache allows you to serve WebP images without JavaScript and also fully supports srcset since WP 4.4. WebP is a new image format that provides lossless and lossy compression for images on the web. How does the caching work? This plugin requires minimal setup time and allows you to easily take advantage of the benefits that come from using native WordPress caching. Dessky Cache has the ability to create 2 cached files. One is plain HTML and the other version is gzipped (gzip level 9). These static files are then used to deliver content faster to your users without any database lookups or gzipping as the files are already pre-compressed. System Requirements PHP >=5.3 WordPress >=4.1 Credits This cache plugin is partially based on Cachify developed by Sergej Müller. Dessky Cache is also based on the ‘Cache Enabler – WordPress Cache’ plugin developed by keycdn. Rocket graphic is made by Vaadin and it is licensed under Creative Commons BY 3.0 .

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.
