LWSCache vs WP-Optimize – Cache, Compress images, Minify & Clean database to boost page speed & performance

This plugin, created by LWS help to automatically manage your LWSCache purge when you edit your pages, post, messages… It provide a way to purge all your LWSCache. This plugin works only on servers using the LWSCache system. This cache is pre-installed with Classic shared web hosting, WordPress hosting and soon cPanel hosting from LWS. The loading speed of your site is crucial to its success. The more visitors your site has, the more RAM and CPU memory the system uses. The page is loaded slowly. So you need a cache system to avoid reloading the page when it is not necessary. In addition, the site’s page load speed is used in Google’s ranking algorithm. So caching plugins that can improve load times will improve your SEO ranking. Low rankings, and therefore insufficient exposure, often do not allow you to make a living from your website. The loading time of most websites is less than three seconds. Beyond that, many users have already left the page. The LWS Cache tool is a system designed and developed by LWS. It optimize the loading performance of your website through the use of advanced caching mechanisms, configured at the server level. The tool uses the technologies provided by NGINX. Functioning When LWS Cache is enabled, a cache server is introduced between the visitor and the web server. The aim is to reduce the number of script executions required. For that it keeps the result of the execution in memory for future requests requiring the same response. This means that the same script is no longer executed several times to achieve the same result. Thus, we eliminate the waiting time of the script execution on the page loading time. At the same time, we save the resources used during the script execution. The visitor requests the page from the web server. Example: index.php. LWS Cache checks if the page has already been generated and stored in the cache If yes, the page is returned directly to the visitor without the need to access the web service and without executing the script If not, the page is requested to be generated on the web service as a result of the script execution (PHP, NodeJS, Perl, Ruby, …). Once the page is generated, LWS Cache determines if the page can be cached (via headers, URL, …) If yes, the page is saved in the cache and returned to the visitor If not, the page is saved in the microcache (short-lived cache) and returned to the visitor Managing LWS Cache with the plugin The WordPress LWS Cache plugin allows you to automatically purge the cache of your pages when you modify them or when you add/approve comments. To manage the plugin, once connected to your WordPress administration console, go to the “Settings” menu and then “LWS Cache”. From the settings page, you can enable/disable automatic emptying. You can define when to automatically empty the LWS Cache and completely purge the cache. A button for emptying the entire cache can be found anywhere in the WordPress admin console (in the quick access bar at the top of the screen). Key Features Several settings are available to manage your LWS Cache, you can enable or disable these settings: Automatic purge Home Page Purge (when a post is modified or added, when a published post is trashed) Purge Post/Page/Custom Post Type (when a post is published, when a comment is approved/published, when a comment is unapproved/deleted) Purge Archives (date, category, tag, author, custom taxonomies) Purge all cache

MORE THAN A CACHING PLUGIN WP-Optimize is trusted by more than 1 million WordPress website owners to boost performance and reduce page load times to improve your site’s user experiences and SERP rankings in Google. It does this in four clever ways: 1. It caches your site Caching is the process of storing a temporary HTML version of your site on the server so it can be retrieved more quickly for the user. It’s a sure-fire way to ensure web pages load at lightning-fast speed. Turn it on in just one click. 2. It compresses images Large images can really impact page speed load times. WP-Optimize makes it easy to identify and compress images to your preferred lossy / lossless settings in a couple of clicks. 3. It cleans the database Your WordPress database stores everything that you need, plus some things that you don’t. WP-Optimize cleans and optimizes the database to speed up your site and save server resources. 4. It minifies On top of its three main features, WP-Optimize Cache also has the more advanced minification feature. Together with caching, minification dramatically improves performance and page speed load time. 1. CACHE YOUR SITE Turn on caching in just one click: WP-Optimize automatically and optimally configures itself for your WordPress site. Turn it on in one-click or refine its settings if you prefer. More cache features: Cache preloading: This feature emulates a visit to your site, meaning cached files are served straight away, speeding up your site from the very first visit. GZIP Compression: When the server isn’t configured to do so, WP-Optimize delivers HTML, CSS and JS files to the user’s browser as smaller, compressed files, reducing the size of pages and style sheets by up to 90%! Preload key requests: Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster [Premium]. Use cache settings to: Serve cached content to logged in users: Turn this on if content stays the same for logged in users (or turn on and exclude URLs where content does change e.g. my account areas). Exclude content from cache: Exclude by URL, conditional tags, browser agent strings or list cookies that should prevent caching when set (advanced user settings). Deliver device-specific cache: Serve separate cache files to desktop and mobile devices . This ensures that responsive features e.g. desktop and mobile menus are cached separately and served correctly. User per role cache: Useful if your website delivers different content to different user roles. e.g. an e-commerce site that displays different content to resellers or consumers [Premium]. User specific cache: Serves separate cache files to individual users. Useful for websites with personalised content e.g. Learning management systems [Premium]. Cache purging permissions: Select which user roles are allowed to purge the cache e.g. admin only or perhaps a ‘teacher’ role in an LMS setting only [Premium]. 2. COMPRESS IMAGES Lossy or lossless compression options: Choose between maximum space saving, best image quality or somewhere in-between. WebP conversion: Recommended by Google, WebP can achieve up to 34% smaller file sizes compared to JPEG and up to 26% compared to PNG. Auto-compress: Check a box and every new image you upload will automatically be compressed to your preferred lossy / lossless settings. Bulk compression: Compress every existing image on your site with the press of a button. Restore original: Gone too far? Revert images back to their original in one click. Retain EXIF image data: Check a box to retain EXIF image data during compression. Lazy Load: Webpages load much faster by loading web parts gradually, when they’re needed vs simultaneous loading of everything, all at once [Premium]. Delete orphaned images: Identify and delete unused images from your WordPress website, saving disk space [Premium]. Delete unused image sizes: WordPress creates multiple sizes for every uploaded image causing the uploads folder to become bloated. Scan for image sizes not in use and remove them to save further disk space [Premium]. 3. CLEAN AND OPTIMIZE THE DATABASE Cleans-up database tables, post revisions, auto draft posts, trashed posts, spam, trashed comments and more. Choose what to optimize or it’s one click to clean out the lot. Schedule clean-ups: So you can set and forget. Choose from daily, weekly, fortnightly or monthly. Flexible clean-up schedules: You may wish to optimize database tables more frequently than you remove unapproved comments (for example). Choose the specific time and day when tasks should run [Premium]. Retain a set number of weeks’ data during clean-ups: Just in case you need to retrieve something. Back up before clean-ups: If you delete something you shouldn’t, restore it in a couple of clicks with UpdraftPlus. Power tweak – Turbo boost for WooCommerce: Unique to WP-Optimize, this power tweak boosts performance by replacing a slow query in WooCommerce with two much more efficient queries. E-commerce sites transacting high numbers of orders stand to gain here [Premium]. Power tweak – Boost performance by indexing the postmeta table: This unique power tweak works by allowing the WordPress postmeta table to be indexed, improving performance [Premium]. 4. MINIFY AND COMBINE HTML, CSS AND JAVASCRIPT Minify in just one click: Minifies HTML, JavaScript and CSS. Toggle on or off or customise each one under ‘settings’. Customise minification: Minify only (removing unnecessary code e.g line breaks and white spacing) or minify and merge. Apply the same or different settings to HTML, CSS and JavaScript. Asynchronous loading: Choose non-critical CSS and JavaScript files to load in the background and independently of other resources e.g. analytics or pixel scripts. Loading asynchronously eliminates render blocking and improves page speed. Exclude files from being minified: Specify CSS and JavaScript files to exclude from minification. Optimize fonts: Optimize Font Awesome and Google Fonts. Inline the font files, inherit from CSS settings or load CSS / Javascript asynchronously instead. Preload assets: WP-Optimize visits each web page on your site so the code is minified and preloaded for real life users, right from their very first visit. Preload key requests: Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster. WHY WP-OPTIMIZE?
