You might have a look at the WordPress Transient API. You should be able to store your shortcode output $total_network with set_transient( ‘my_shortcode_cache’, $total_network, WEEK_IN_SECONDS ); where WEEK_IN_SECONDS is a built in constant equal to 604800. You can then fetch it with: get_transient( ‘my_shortcode_cache’ ); If you need it to work network wide there exists … Read more
The most common thing to try is a content caching plugin like W3 Total Cache or WP Super Cache. Both will cache entire pages to disk, and will allow the Apache web server to completely bypass PHP processing for many page views. With W3 Total Cache, you can also cache system objects and the results … Read more
Static page cache is trade-off of resources for speed. The larger and more complex site is, the more resources it takes to cache it. Since there is no such thing as unwanted speed, static cache of small sized site is one of the best performance improvements possible. Especially on shared hosting where other tweaking options … Read more
The wp_posts table has a post_content_filtered column that plugins can use to cache expensive post content filters. The idea is that when you display the page, you don’t read post_content but you read post_content_filtered. This is nice, but it won’t solve your search problem because WordPress by default only looks at post_content and post_title. You … Read more
I’d say your third option is the way to go. Incidentally, why did you roll your own static cache in taxonomy_image_plugin_get_associations() instead of using the built-in WP_Cache API for that? Is there a reason wp_cache_get wouldn’t work here? Seems like using the WP object cache would optimize better when people do have caching plugins turned … Read more
I guess the answer is that HHVM does not work with typical opcode caching, the compiler is not the same as “regular” PHP’s. HHVM has it’s own opcode caching that as far as I know does not integrate with APC or Zend’s OPcache, it does it’s own thing. In other words, it would be redundant. … Read more
There are two steps necessary to make sure that the browsers fetch the updated HTML pages (ex: home page). Step 1 Uncheck ‘Set expires header’ at your site’s wp-admin/admin.php?page=w3tc_browsercache#html_xml, for ‘HTML & XML’ files. Whenever a browser sees an Expires header, it (the browser) will fetch the next version of that particular HTML page only … Read more
okay, here we go. try this: in your functions.php modify the behaviour of ai1ec_options: $ai1ec_options = get_option(‘ai1ec_options’); delete_option(‘ai1ec_options’); add_option(‘ai1ec_options’, $ai1ec_options, ”, ‘no’); // thanks for your suggestion 🙂 be careful though, as you might lose your set options, so be sure to get them from the database first. or create a backup option. afterwards, clear … Read more
Template tags rely on global $post (unless you explicitly provide something else to those that support it. So either: they get something from that variable (no reason to go for it in database) or they don’t (then they fail because they have no clue what you want) Under most normal circumstances there is no reason … Read more
The Transient API saves data inside the database, which isn’t as effective as APC, but a similar workflow as used for transients can be used for APC. It is important to check if APC is available and active, so its functions are usable. Because this isn’t always the case, it is to consider to add … Read more
