💡 Recommendation: On shared hosting, increase the timeout to 500ms and reduce the batch to 5.On a VPS or dedicated server, you can use a 0ms delay and a batch size of 20-50.
⑨ Notification emails
The module can send a report email at the end of each warming (via the Back Office or via CRON).
- In the tab Settings , check Receive an email after each warming
- Enter recipient email address
- Optional: set an alert threshold (e.g., 10%).If the error rate exceeds this threshold, the email subject is prefixed
[ALERT]
- Click on Save settings
⚠ Prerequisites: Email sending uses your PrestaShop's SMTP settings (Advanced Parameters > Emails).If your PrestaShop emails are working (order confirmations, etc.), the module will work too.
⑩ FAQ - Frequently Asked Questions
Does warming slow down my site for visitors?
The module consumes server resources during warming, but the delay between each request (configurable) prevents overloading the server.Launch the warming during off-peak hours to avoid any impact.
How long does a full warming take?
This depends on the number of pages and the configured deadline.Real-world example: 438 pages with a 200ms delay = approximately 8 minutes.5000 pages with a 0ms delay = approximately 15 minutes.
Does the module work with Varnish / Redis / Memcached?
Yes.The module visits pages like a classic browser.Any cache system (Varnish, Redis, Memcached, Smarty, FileSystem) will be filled by module visits.
Can I start the warming automatically overnight?
Yes, that is exactly what CRON scheduling is for.Configure the time and days, copy the CRON URL, and the warming runs by itself while you sleep.
Does the module modify my product/category data?
No, never. The module only visits your pages in read-only mode (GET).It does not modify any data in your shop.Uninstalling only removes the module's tables (history, configuration).
I have 500 errors in the report.Is this the module?
No.The module visits the page exactly like a browser.If the page returns a 500 error, it is crashing for your visitors too.The report helps you detect these problems.
PrestaShop cache is disabled, does warming still work?
Technically yes (the pages are visited), but without caching enabled, nothing is cached.The module warns you with a notice on the dashboard and during the pre-check.
