This includes database optimizations, errorlog review, automatic cache purging, automatic image optimization and resizing, performance recommendations, and support for down stream HTML caching. Specifically, Servebolt Optimizer does two things for your site: 1. It connects your [WordPress hosted](https://servebo.lt/e3ke3) or [WooCommerce hosted](https://servebo.lt/724lz) Servebolt site to your [Servebolt Admin Panel](https://servebo.lt/pf3hu). 2. Its features implement Servebolt’s best practices for performance. These best practizes include database optimizations, error log review, automatic cache purging, automatic image optimization/resizing, performance recommendations and support for down stream HTML caching. This project is maintained on [Github](https://servebo.lt/sog). ### Features * Configures HTML caching to speed up your site (**Servebolt clients only**) * Integrates with [Accelerated Domains](https://servebo.lt/4c9dw) (**Servebolt clients only**) * Rewrite headers to allow down stream HTML caching (**Servebolt clients only**) * View Apache/PHP error log (**Servebolt clients only**) * Database optimization – Convert tables to InnoDB * Database optimization – Add performance improving indexes * Automatic cache purge for Cloudflare and Accelerated Domains * Recommendations on additional performance improvements * Multi-site support * WP CLI support * Cloudflare Image Resize-support (beta feature) * WP Rocket compatability (**Servebolt clients only**) Read more about the plugin and all its features in our [Help Center](https://servebo.lt/servebolt-optimize-documentation). ### Accelerated Domains The integration with our revolutionairy add-on performance and security enhancing service [Accelerated Domains](https://servebo.lt/4c9dw) is made possible by Servebolt Optimizer. Installing the Servebolt Optimizer will provide the required HTTP headers to make use of Accelerated Domains. ### Automatic purge of Cloudflare cache Servebolt Optimizer supports the most complete solution for Cloudflare cache purging. The HTML Cache is automatically purged when any post type or term has been updated. You can also purge directly from the admin bar. This Cloudflare integration supports both the use of API key and API token authentication when communicating with the Cloudflare API. ### HTML Caching This plugin rewrites HTTP headers of HTML to allow for HTML Caching, and for the browser to cache HTML. HTML Caching may introduce all sorts of problems for end users, so installation and testing should be performed by a professional. ### Configuration This plugin can be controlled via the WordPress Dashboard or WP CLI. Additionally there are various filters and PHP constants at your disposal. ### Filter and constant reference The plugin has various filters and PHP constants that allows third-party developers to alter the behaviour of the plugin. Please read the article [Filters and PHP constants](https://servebo.lt/servebolt-optimizer-filters-and-php-constants) in our help center to learn more. ### Testing We test against the current production version of WordPress and the next beta/development version ## Installation Navigate to your WordPress Dashboard > Plugins > Add New and then search for **Servebolt** and follow instructions. Alternatively, you can also install Servebolt Optimizer via sFTP or WP CLI: With sFTP: 1. Download this plugin and unzip 2. Upload servebolt-optimizer folder to the `/wp-content/plugins/` directory 3. Activate the plugin through the ‘Plugins’ menu in WordPress 4. Navigate to Servebolt > Performance Optimizer and run optimizations if necessary With WP-CLI: 1. Log in to your site with SSH 2. cd to your sites root wordpress folder 3. Run `wp plugin install servebolt-optimizer --activate` 4. Run optimizations `wp servebolt db optimize` Run `wp help servebolt` to see all the available commands that can configure the plugin. ## FAQ ### Will Servebolt Optimizer plugin make my site faster? The Servebolt Optimizer plugin is primarily designed to make best use of our [WordPress hosting](https://servebo.lt/e3ke3) or [WooCommerce hosting](https://servebo.lt/724lz). Its database optimizing feature does indeed help in making your database faster and thus your site. ### Can I install this plugin if I’m not a Servebolt client? Yes, you can. The database optimizations are beneficial for everyone as well as the Cloudflare cache purge options. You would miss out on the [fastest WordPress hosting out there](https://servebo.lt/5xbqg), but you can use it on a non-Servebolt site. ### What if I discover a bug? If you’re a Servebolt client, please reach out to our Support Team and we’ll be happy to help you out there. Alternatively, you can create a support forum request [here](https://wordpress.org/support/plugin/servebolt-optimizer/). ## Reviews ![](https://secure.gravatar.com/avatar/5142cce917d013f6ebf582bb91e25dca81dcff4cd76d81caa3900b75b44a2444? s=60&d=retro&r=g) ### 󠀁[Works great!](https://wordpress.org/support/topic/works-great-9387/)󠁿 [ingarb](https://profiles.wordpress.org/ingarb/) ސެޕްޓެމްބަރ 24, 2024 Great optimization plugin for Servebolt users! ![](https://secure.gravatar.com/avatar/3e08228deb5e6fb3c4363cb718b0d0ca2db0b8c4b6c50050211019318668c2ef? s=60&d=retro&r=g) ### 󠀁[Excellent Plugin](https://wordpress.org/support/topic/excellent-plugin-7294/)󠁿 [ljgarnes](https://profiles.wordpress.org/ljgarnes/) އޯގަސްޓް 17, 2021 This Plugin is the awesome!

There is now options to limit Cache tag purging for Shop Page, Post archives, Product categories, Term, and other public taxonomy pages #### 3.6.2 * New (Accelerated Domains): Introduced “WooCommerce homepage purge” in Cache Cache Settings (disabled by default). Automatically purges the homepage only on product create, delete, or out-of-stock events. #### 3.6.1 Variable Edge Caching (Requires Accelerated Domains) We’ve introduced support for Vary Headers Caching, unlocking smarter edge caching with Accelerated Domains. It allows cache separation at the edge based on specific request headers, enabling personalized content delivery without sacrificing cache performance. Instead of serving one generic cached version to every visitor, your site can now cache and deliver the right version instantly — without bypassing cache or adding backend complexity. This means: Personalized experiences at full edge speed Higher cache hit ratios No performance trade-offs New Cache Variation Options Available under: Servebolt Optimizer Cache Cache Settings (Visible when Accelerated Domains is enabled) You can now vary cache based on: Device (User-Agent) Automatically separates cache for Mobile, Tablet, and Desktop visitors. Browser Language (Accept-Language) Serves the correct language version based on the visitor’s primary browser setting. Visitor Country (X-Origin-Country) Enables country-specific content, pricing, or campaigns — fully cached at the edge. These variations can be enabled individually or combined, depending on your site’s needs. New: Purge PHP OPcache Button Added a dedicated “Purge PHP OPcache” button directly in the WordPress admin. This allows you to clear PHP OPcache instantly without SSH access or manual intervention — making deployments and troubleshooting faster and easier. #### 3.5.59 * Bugfix: clear-site-data header should now always be sent no matter the browser type * Bugfix: Menu Optimizer – Added a guard so the cache-indicator comment isn’t appended when the cached payload isn’t a plain string or is already serialized, preventing Timber’s unserialize() warning etc. #### 3.5.58 * Error Log Viewer: Grouped errors with a smart, tabbed PHP/HTTP overview. Automatic level selection (Fatal Error All), level chips with counters, strict 2,500- line scan, and pagination options (100/250/500).
