What does the 'Listing refresh interval' mean exactly?

Hi there,

It sets how often the popular list is updated on the sidebar.

The Live option will have WPP update the listing every time a post is viewed, while the other options will make WPP cache the popular list for the selected time (eg. 1 hour) before updating the ranking again. This will make WPP make less queries to the database, which is desirable for large sites with lots of visits to avoid slowdowns.

Héctor, Thanks very much. I know it now.

I’m using wpp_get_mostpopular() on the siderbar. Does the ‘Listing refresh interval’ option also affect it?

And what’s difference between the WPP cache and other WordPress Cache plugins (such as WordPress Super Cache or W3 Total Cache)? Sorry for so many questions.

Yep, that’s correct.

Cache plugins such as W3 Total Cache are capable of creating static files from your posts and pages to avoid making calls to the database, making your site “static” (no dynamic content is loaded unless necessary).

WordPress Popular Posts, on the other hand, takes advantage of the Transients API to store database query results into WordPress’ options table for a fixed amount of time. After the transient times out, WPP queries the database again to update the popular posts list. As you can guess, this is good for performance because the plugin doesn’t have to run complex queries every time the widget is loaded on your site.

Hope that clears it up ??
