Usage
Dashboard Widget
The Queue Optimizer dashboard widget appears on your WordPress admin dashboard and shows:
- Health Status – Overall queue health (Healthy, Backlog, or Needs Attention)
- Pending Actions – Number of actions waiting to be processed
- Running Actions – Actions currently being processed
- Failed Actions – Actions that failed in the last 24 hours
- Run Queue Button – Manually trigger queue processing
Settings Configuration
Time Limit (10-300 seconds)
Controls how long ActionScheduler processes tasks in each batch. Recommended values:
* Shared hosting: 30 seconds
* VPS/Managed: 60 seconds
* Dedicated/High: 120 seconds
Concurrent Batches (1-10 batches)
Determines how many background processes run simultaneously. Recommended values:
* Shared hosting: 2 batches
* VPS/Managed: 4 batches

FAQ
-
How does this plugin improve performance?
-
It optimizes key ActionScheduler settings that control how WordPress processes background tasks. This results in faster image optimization, smoother WooCommerce operations, and better handling of any background processing.
-
What is the dashboard widget?
-
The dashboard widget provides a quick overview of your queue health directly on your WordPress admin dashboard. It shows pending, running, and failed action counts, plus a button to manually run the queue.
-
How does server detection work?
-
The plugin analyzes your PHP memory limit and max execution time to determine if you’re on shared hosting, VPS/managed hosting, or a dedicated/high-performance server. It then recommends optimal settings for your environment.
-
Will this affect my website’s front-end performance?
-
No. This plugin only affects background task processing and has zero impact on your website’s front-end performance. It actually improves overall site responsiveness by making background tasks more efficient.
-
Is this compatible with my existing plugins?
-
Yes. This plugin works with any plugin that uses ActionScheduler, including Elementor, WooCommerce, image optimization plugins, and backup plugins. It enhances their performance rather than conflicting with them.
-
Do I need to configure anything after installation?
-
The plugin works with sensible defaults immediately after activation. However, you can use the “Apply Recommended Settings” button to optimize for your specific server environment.
-
What happens if I deactivate the plugin?
-
All optimizations are immediately removed and ActionScheduler returns to its default behavior. Your site will continue working normally, just without the performance enhancements.
-
Yes. The plugin detects shared hosting environments and recommends conservative settings that are safe for limited resources.
-
How do I know if it’s working?
-
Check the dashboard widget for queue health status, or visit Tools > Queue Optimizer to see current settings and queue statistics. After activation, image processing and background tasks should be noticeably faster.
-
What do the health statuses mean?
-
- Healthy (green) – Queue is processing normally with no issues
- Backlog (yellow) – More than 50 pending actions; consider running the queue manually
- Needs Attention (red) – Failed actions detected in the last 24 hours; investigate the ActionScheduler logs
