Javascript has a HTML based method for deferring and asynchronously loading files, namely script Defer and script Async. Unfortunately these HTML solutions do not work for CSS files.
But do not worry, this plugin allows you to lazy load yous css files. Thus speeding up your initial view experience for visitors and search engines.

ALTOS speeds up the WordPress admin by giving you per-screen control over which active plugins are actually loaded. Most WordPress sites accumulate dozens of plugins over time, but only a few are needed on any given admin screen. Loading them all on every page wastes memory, time, and database queries.
ALTOS operates at the WordPress core level via the MU-plugins mechanism, intercepting the loading pipeline before WordPress fully initialises. It cleanly skips heavy code paths on screens where they aren’t needed — while preserving admin menus, dependency relationships, and safety guards.
Key features
<ul>
<li>Per-screen control — Set rules for each admin screen (Dashboard, Posts, Pages, Settings, WooCommerce, Custom Post Types, …).</li>
<li>Three states per rule — Enabled (always load), Disabled (never load), Defer (load after the main page).</li>
<li>Smart menu preservation — Admin menu entries stay accessible for blocked/deferred items via an automatic snapshot system.</li>
<li>Hierarchical rules — Global → group → screen, with intelligent inheritance.</li>
<li>Automatic mode with suggestions — Confidence-scored recommendations from real performance samples; you review and apply manually.</li>
<li>Dependency cascade detection — Catches dependent items when a parent is blocked.</li>
<li>Request-type optimisation — Separate rules for AJAX, REST API, WP-Cron, and WP-CLI.</li>
<li>Update Optimizer — Three strategies to reduce update-check overhead without breaking badge counts.</li>
<li>Per-plugin performance metrics — Real-time load time, DB queries, memory.</li>
<li>Developer tools — Admin drawer, admin-bar integration, REST endpoints, extensive filters/actions.</li>
<li>Built-in translations — Czech, Slovak, Polish, German, French, Spanish.</li>
</ul>
Typical impact
<ul>
<li>30–50 % faster admin pages.</li>
<li>20–40 fewer database queries per admin page.</li>
<li>1–5 MB less memory per blocked item.</li>
</ul>
Safety by default
<ul>
<li>Manual mode requires explicit rules — nothing is changed without your action.</li>
<li>Automatic mode only suggests — never applies on its own.</li>
<li>The loader protects itself from being blocked.</li>
<li>Page-builder bypass for Elementor, Bricks, Divi, Beaver Builder during active editing sessions.</li>
<li>Emergency recovery URL for one-click bypass if a misconfiguration breaks the admin.</li>
</ul>
<h3>External Services</h3>
This plugin does not contact any external services. It does not send analytics, telemetry, license checks, or any other network requests. All rules, samples, snapshots, and configuration are stored exclusively in your own WordPress database.
The “Update Optimizer” feature exclusively throttles the standard WordPress update-check HTTP requests to <code>api.wordpress.org</code> — it never adds new endpoints and never sends additional data.
<h3>Privacy</h3>
ALTOS stores all of its data in your own WordPress installation:
<ul>
<li>Rules and configuration are stored in the WordPress options table.</li>
<li>Performance sampling data is stored in a plugin-owned custom table (<code>{prefix}sapm_sampling_data</code>) with 30-day retention.</li>
<li>No personal data about visitors or administrators is collected.</li>
</ul>
The plugin does not transmit any data to external services and does not contact any external endpoints other than throttling WordPress’s existing <code>api.wordpress.org</code> update checks when the (opt-in) Update Optimizer is enabled.
