I have multiple wordpress specific queries firing when a user visits my homepage. I could have 150+ users visit concurrently with maybe 25+ of them hitting the homepage.
Here is an example of one query:
$args = array( 'posts_per_page' => 3, 'post_status' => 'publish', 'category' => 37, 'meta_key' => 'total_views', 'orderby' => 'meta_value_num', 'order' => 'DESC', 'date_query' => array( array( 'after' => '1 month ago' ) ) );
I have roughly 6 of those queries (and similar ones) on the Homepage.
I've recently been implementing phpfastcache across most areas of the site and for the most part it has worked really well (especially with lowering entry process limits).
I did hear that wordpress queries are generally well optimized and there is usually no point in caching them.
Does this still hold true in my case?
1 queries is cached for 10 minutes.
2 queries are cached for 60 seconds each (they are part of a "here is a recently updated section"). I could in theory increase this slightly.
The rest are cached for half a day (which could be increase to a day or two potentially).
