Preload function doesn’t cache all content

Hello,

we recognized, that even with Preload setting activated, the cache is not created for all the content.

It’s the currect WPFC version 0.8.9.4 on WP 5.1.1 with about:
– 120 published pages
– 40 published posts in 9 categories
– 2590 published products in 420 categories (WooCommerce)

Is it possible that the Preload setting doesn’t work correct with this amount of products? Because we set the setting to the maximum of 12 per minute (and for testing via wp-config to 30), because the site is on a managed server, but even one day later there are pages that aren’t cached on the first visit.

Now there is no time set, where the cache is deleted automatically, but the Preload function is set to start from the beginning when Preload has ended, to minimize outdated content.

Also it would be nice to make the two “Delete Cache” links in the admin bar hidable (e.g. via checkbox in the settings) or at least show a warning message to confirm, because now the cache is nearly empty. Maybe I accidentally deleted the whole cache when I wanted to clear the cache for one single page only.

I checked it now, in 5 minutes (with Preload set to 12 per minute) the cached products increased from 102 to 118, five minutes later it’s now 132 products, checked via FTP. I don’t know which way the Preload function goes to cache, because of that I’m aware that the Preload function can have cached other content in this time too.

Thank you in advance.
