<p><strong>365i Queue Optimizer</strong> is an ultra-lightweight WordPress plugin designed to optimize ActionScheduler performance for faster image processing and background task execution. Now featuring revolutionary JavaScript-based post-upload processing that eliminates upload slowdowns. Perfect for sites using image optimization plugins, WooCommerce, or any plugin that relies on ActionScheduler.</p>
<h3>What This Plugin Does</h3>
<p>This plugin applies three essential ActionScheduler optimizations:</p>
<ul>
<li><strong>Time Limit Control</strong> – Sets how long ActionScheduler processes tasks (default: 60 seconds, configurable 10-300)</li>
<li><strong>Concurrent Batch Processing</strong> – Controls simultaneous background processes (default: 4 batches, configurable 1-10)</li>
<li><strong>Image Processing Engine</strong> – Prioritizes your chosen image processor (GD or ImageMagick)</li>
</ul>
<h3>Key Features</h3>
<ul>
<li><strong>Ultra-Lightweight</strong> – Only 5 files, minimal server impact</li>
<li><strong>Zero Overhead</strong> – No complex dashboards, logging, or debugging features</li>
<li><strong>Simple Configuration</strong> – Clean settings page under Tools > Queue Optimizer</li>
<li><strong>Instant Results</strong> – Optimizations apply automatically after activation</li>
<li><strong>WordPress Standards</strong> – Follows all WordPress coding and security standards</li>
<li><strong>Performance Focused</strong> – Based on proven optimization techniques</li>
</ul>
<h3>Perfect For</h3>
<ul>
<li><strong>Image Optimization</strong> – Faster processing with Elementor Image Optimizer, Smush, ShortPixel, etc.</li>
<li><strong>WooCommerce Sites</strong> – Better handling of product imports, order processing, and bulk operations</li>
<li><strong>High-Volume Sites</strong> – Improved performance for sites with large background task queues</li>
<li><strong>Plugin Compatibility</strong> – Works with any plugin that uses ActionScheduler</li>
</ul>
<h3>Philosophy</h3>
<p>Simple, fast, and effective. This plugin does one thing well: optimize ActionScheduler performance with minimal overhead and maximum compatibility.</p>
<h3>Usage</h3>
<h3>Settings Configuration</h3>
<p><strong>Time Limit (10-300 seconds, default: 60)</strong><br />
Controls how long ActionScheduler processes tasks in each batch. Higher values process more tasks per run but may impact server performance. Lower values are safer for shared hosting.</p>
<p><strong>Concurrent Batches (1-10 batches, default: 4)</strong><br />
Determines how many background processes run simultaneously. More batches can speed up processing but increase server load. Start with 4 and adjust based on your server capacity.</p>
<p><strong>Image Processing Engine (GD or ImageMagick, default: GD)</strong><br />
Prioritizes your chosen image processing library. GD is more universally compatible, while ImageMagick often provides better quality and performance for image operations.</p>
<h3>Current Status</h3>
<p>The settings page shows your current optimization status, including:<br />
* Whether optimizations are active<br />
* Current ActionScheduler processing time limit<br />
* Number of concurrent batches configured<br />
* Selected image processing engine</p>
