Performance Lab

विवरण

The Performance Lab plugin is a collection of features focused on enhancing the performance of your site, most of which should eventually be merged into WordPress core. The plugin facilitates the discovery and activation of the individual performance feature plugins which the performance team is developing. In this way you can test the features to get their benefits before they become available in WordPress core. You can also play an important role by providing feedback to further improve the solutions.

The feature plugins which are currently featured by this plugin are:

These plugins can also be installed separately from installing Performance Lab, but having the Performance Lab plugin also active will ensure you find out about new performance features as they are developed.

सामान्य प्रश्न

What is the purpose of this plugin?

The primary purpose of the Performance Lab plugin is to allow testing of various performance features for which the goal is to eventually land in WordPress core. It is essentially a collection of “feature plugins”, which makes it different from other performance plugins that offer performance features which are not targeted at WordPress core and potentially rely on functionality that would not be feasible to use in WordPress core. The list of available features will regularly change: Existing features may be removed after they have been released in WordPress core, while new features may be added in any release.

Can I use this plugin on my production site?

Per the primary purpose of the plugin (see above), it can mostly be considered a beta testing plugin for the various performance features it includes. However, it’s essential to understand that utilizing it comes with inherent risks. Users are encouraged to proceed with caution and understand that they are doing so at their own risk.

Where can I submit my plugin feedback?

Feedback is encouraged and much appreciated, especially since this plugin is a collection of future WordPress core features. If you have suggestions or requests for new features, you can submit them as an issue in the Performance Lab GitHub repository. If you need help with troubleshooting or have a question about the plugin, please create a new topic on our support forum.

Where can I report security bugs?

The Performance team and WordPress community take security bugs seriously. We appreciate your efforts to responsibly disclose your findings, and will make every effort to acknowledge your contributions.

been using a few of the plugins and metrics for testing and scaling, been using some of the plugins noted there on some production sites, but I do advise on never installing the plugins that require optimization detective. let's hope they make it to core fast!

I have tested this plugin on a few sites and it provides some useful performance features that are helpful for optimization and experimentation. The modular approach is nice and makes it easy to enable or disable specific options. However, the interface and documentation could be improved for better clarity, especially for non-technical users. Overall, it’s a solid plugin with potential, but still needs refinement for a smoother production workflow.

Performance Lab is the gateway to the future of WordPress. These tools are crucial for anyone serious about site speed, Core Web Vitals, and modern image formats. I have personally translated and reviewed 100% of the strings for the entire Performance Lab ecosystem, including all standalone plugins (WebP Uploads, Speculation Rules, View Transitions, etc.) and their respective Readme files. As the PTE (Translation Editor), I’ve ensured that complex technical terms are translated accurately to help the Persian WordPress community implement these performance enhancements with ease. Kudos to the performance team for these high-quality tools! Best regards, @saeidafshari دوستان و توسعه‌دهندگان گرامی، مجموعه افزونه‌های رسمی تیم کارایی وردپرس، شامل ۱۲ ابزار تخصصی برای افزایش سرعت و بهینه‌سازی سایت، به صورت ۱۰۰٪ فارسی‌سازی و بازبینی شد. تمام مفاهیم مدرن مثل قوانین پیش‌بینی مرورگر و بهینه‌سازی تصاویر به دقت معادل‌سازی شده‌اند تا بتوانید بدون ابهام فنی، از آخرین تکنولوژی‌های جهانی در سایت‌های ایرانی استفاده کنید. با احترام، سعید افشاری
