Third Party Compatibility The vast majority of plugins and themes are compatible with LSCache. Our API is available for those that are not. Use the API to customize smart purging, customize cache rules, create cache varies, and make WP nonce cacheable, among other things. Privacy This plugin includes some suggested text that you can add to your site’s Privacy Policy via the Guide in the WordPress Privacy settings. For your own information: LiteSpeed Cache for WordPress potentially stores a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules. In addition to caching, our WordPress plugin has online features provided by QUIC.cloud for Image Optimization and Page Optimization services. When one of these optimizations is requested, data is transmitted to a remote QUIC.cloud server, processed, and then transmitted back for use on your site. QUIC.cloud keeps copies of that data for up to 7 days and then permanently deletes it. Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to LiteSpeed so that we may better provide technical support. None of these features collects any visitor data. Only server and site data are involved. QUIC.cloud CDN, if enabled, uses LSCache technology to access your site, and serve your content from remote global nodes. Your data is not accessed by QUIC.cloud employees in any way, except as necessary in providing maintenance or technical support. Please see the QUIC.cloud Privacy Policy for our complete Privacy/GDPR statement.

How fast is your web host? Dozens of PHP speed tests, 1 overall grade: The easy way to compare hosting performance. Bringing Transparency to Your Web Host’s PHP Performance The faster your websites run, the better. Better SEO, better UX, better returns on your effort. But in any PHP-based system (including WordPress, Drupal, Joomla, Magento, and many others) there’s an important performance factor that’s hard for you to see and mostly beyond your control. It’s your web hosting. How fast does PHP run on the infrastructure that your web host provides? PHP Vitals gives you a simple way to find out. A Free, Quick and Easy Speed Test In a minute or two, PHP Vitals analyses exactly how well your server performs on dozens of different tests of PHP performance. When you run PHP Vitals you’ll see an overall grade, and you can see where your web host belongs on the PHP Vitals leaderboard. You can’t see your server hardware. You don’t know how many others are sharing your resources. You don’t know if your hosting is rate-limited, over-provisioned, or dependent on ancient CPUs. PHP Vitals lifts the lid on what you’re really getting for your money. What Gets Tested PHP Vitals focuses on base PHP functions. Base categories are: – php_features – math – string – array – crypto – file – serialization Specific operations that are tested include: – PHP Class (getter/setter). – Public properties and methods. – Simple math operations. – Complex math operations. – String concatenations. – Regular expressions (regex). – Functions: explode, strpos. – Operations: Array sorting, set, unset, copy, and others. – Password hashing. – MD5 hashing. – SHA256 hashing. There are no MySQL or database benchmarks included. Features PHP Vitals suite of PHP performance benchmarking tests usually takes only 1-2 minutes to run. The tests give you live performance data. Each time you run PHP Vitals you’ll see a breakdown of individual test data and an overall grade (A+ to F). Test data is objective, for example the time taken for each test. Grades are based on the overall time taken. The subjective grading scale is likely to change over time (e.g. an A in 2025 is unlikely to still be an A in 2027). With the option to submit test results to the PHP Vitals leaderboard, you can let developers around the world see a summary of your results, and the hosting provider that it came from. Sharing is optional and no personal data is collected, shared or stored. PHP Vitals data is presented through a beautiful and responsive admin interface. Run and share tests on demand, and build up a history of performance grades over time. Usage on WordPress PHP Vitals is very straightforward. Install the plugin, open “PHP Vitals” from the main menu in your WordPress admin dashboard, and click “Run Benchmark”. External services This plugin connects to PHP Vitals to compare the user’s benchmark test results (This is an optional service).
