How does the Cache section work, please?

Hi,

This is just to clear these caches?

When you press the Clear button, the checked checkbox items will be cleared.

When should I clear them?

It’s when you think the cache sizes are too big.

What happens if I clear HTTP request?

Caches for external HTTP requests that the plugin makes will be cleared. When the plugin output function is called and it will look for a cache first and if not found, it will perform an HTTP request to access an external server such as the PA-API server.

Does it improve my GTMetrix results?

Do you mean some page load performance tests? If the plugin cannot find caches, then it will try to access the Amazon server to fetch data by making an HTTP request, which takes some time and slows down the page load which includes a plugin function call to render products. In other words, with caches, it will be faster and without them, will be slower. Moreover, using caches saves the API calls to prevent you from reaching the rate limit, plus other server resources such as CPU usage, network bandwidth etc.

Caching Mode… I believe I have Cron desactivated. Does it mean I should use Intense? What are the implications?

If you disable WordPress Cron, you want to choose Intense. Otherwise, the products will never be updated. Updating caches are done in the background. For background tasks, the WP Cron mode uses WP Cron and the Intense mode uses the plugin method. The Intense mode will call the renew routine in the background right away when the plugin output function is called and it finds its cache is expired. This means that a background page load is made per cache renewal event. On contrary, the WP Cron mode queues a renew task so that those queued tasks will be handled by WP Cron all at once in a single page load. So the Intense mode is more resource-intensive compared to the WP Cron mode.

What is advisable for this?

The bottom line is you want to use the plugin caches, especially to reduce the chances to reach the PA-API rate limit. If your host limits the database size to 1GB or something, then you definitely want to set the Maximum Overall Cache Sizes to something lower than 1GB.

Hi,

Thank you very much for your fast reply. Now I understand much better this great plugin.

You’re welcome! Glad it helped!

@mmpineda Would be appreciated if you could take a few minutes to write about the plugin. Thank you!
