Styles and scripts are always set up by the functions wp_enqueue_script() and wp_enqueue_style(), which have to be tied to a particular action hook in order to function. I took a peek inside Contact Form 7, and it looks like it’s using action tags of wpcf7_enqueue_scripts and wpcf7_enqueue_styles to add them to the wp_print_scripts and wp_print_styles … Read more
Meanwhile, I found some plugins and tools that can help with this: Query Monitor Laps Debug Bar with some add-ons(Slow Actions, Rewrite Rules, etc.) If you really wanna go deep, try using Webgrind. Not the most friendly tool, but it’ll do the job. Be aware that some of this tools will also have an impact … Read more
The size of the table isn’t really the issue, the queries you’re running on that table might be. For example, if you’re selecting users based on data stored in the user-meta table, then that query will be highly unoptimized, because meta_value is not an indexed field. In which case you may need to add extra … Read more
Basic answer to “what plugin” would probably be W3 Total Cache. It is one of the most functional and actively developed plugins at moment. However complete performance chain is much longer that WordPress plugin alone can handle. Web server (Apache or something else) configuration (response time, time to first byte, headers). Database (time spent processing … Read more
You can check by looking at the size of the rewrite_rules option in the database. If it’s small (which I believe it should with this structure), you’re not using verbose rules. By contrast, if you see several lines per static page, you’re using verbose rules and it’s not good.
You can delete all post via $wpdb DELETE FROM wp_posts WHERE post_type=”post_type”; DELETE FROM wp_postmeta WHERE post_id NOT IN (SELECT id FROM wp_posts); DELETE FROM wp_term_relationships WHERE object_id NOT IN (SELECT id FROM wp_posts) or use this query replace it with {{your CPT}} with your Custom Post Type DELETE a,b,c FROM wp_posts a LEFT JOIN … Read more
Profiling with Profiler-Plugins Not sure exactly what you need to accomplish with your profiling, but WP Tuner (WordPress Plugin) goes a long way to finding what is slowing down your WP install. It looks at each plugin and give your the memory, CPU time and SQL queries involved. The SQL Monitor (WordPress Plugin) analyzes SQL … Read more
Update: The reason the query is being logged is it doesn’t use an index. The query time is 0, i.e. it actually executes fast. You can unset the “log-queries-not-using-indexes” option if you don’t want these to be logged. The wp_options table has no index on autoload (it now should, it was added to WP core … Read more
The answer that yes, the theme_mod functions will be slower, but not significantly, and the benefits outweigh the differences. Theme mods are stored as options. So, in essence, the theme_mod functions are wrappers around the options functions. First, understand that theme_mod settings are stored as an array in a single option, keyed to the specific … Read more
late answer From a brief look: You’d have to use include( admin_url().’load-scripts.php’ ); and include( admin_url().’script-loader.php’ ); Then jump into $GLOBALS[‘wp_scripts’]: Use… $wp_scripts->default_dirs( array_merge( $wp_scripts->default_dirs ,array( ‘/themes/your_theme/js/’ ) ); …to extend it. And then use $wp_scripts->add( $handle, $path_from_content_dir, false/array( $deps ), $ver ) to add a script. Notes: Uncompressed scripts get searched by .dev.js (when … Read more
