Hi @alexlii1971,

Enabling preload cache for Nginx FastCGI Cache is quite straightforward! You just need to check the "Preload Cache" option in the Nginx Helper plugin settings.

Here's how to do it:

1. Go to Settings > Nginx Helper in your WordPress dashboard
2. Under the "Purging Options" section, make sure you've selected "Enable Purge" and chosen "Nginx FastCGI Cache"
3. Check the box next to "Preload Cache" (see screenshot below)
   
4. Click "Save All Changes"

The preload functionality works out of the box with the standard Nginx FastCGI Cache setup, so no additional Nginx configuration is needed.

Hi @Vedant-Gandhi,

Thanks so much for your reply.

To better manage memory and CPU usage, it would be great if you could clarify how it works,since I just note there are a lots of Memory usage on server, and lots of queries internally after enable preload.

I am not sure if it is relevant to preload cache on Nginx helper. Anyway, it would be much helpful for us do anything forehand.

Thanks

Hi @alexlii1971,

Looks like you're seeing a spike in queries after enabling preload for the first time. This is completely normal! The preload process sends a batch of requests only during initial activation, which temporarily increases memory usage and query count. Once preload completes, these numbers will return to normal levels. This is a one-time event that happens when the feature is first activated.
