USE INFORMATION_SCHEMA; 
SELECT table_name,table_rows,data_length FROM TABLES where table_schema = 'DBNAME' AND table_rows > 0 ORDER BY data_length DESC LIMIT 0,50;

This will produce a list like the following (see below). You can adjust the sort order and limit based on your needs. This query isn’t all that helpful in cases of small installs. But in an installation with 500+ tables it can help you narrow down the issue quickly. WARNING: this query can take a long time to run depending on the number of databases on your server and the number of tables in the Dbs.

I just pushed Simplr Registration Form Plus 2.1.9 … lots of behind the scenes updates and code fixes. Primary visual enhance is the UI for the TinyMCE shortcode button. You know longer have to type in the custom fields. You can know just check the boxes then drag and drop to reorder.

function get_template_part_cached($slug, $name, $key, $group = 'posts', $ttl = 3600) {
	if( !$output = wp_cache_get($key, $group)) {
		ob_start();
			get_template_part($slug,$name);
		$output = ob_get_contents();
		ob_end_clean();
		wp_cache_set( $key, $output, $group, $ttl );
	}
	echo $output;
}

But what occurred to me about Thesis, is that it really should be one of the more performant themes out there.  The logic of the theme is organized hierarchically. Thesis passes all html output through thesis_html_framework() which means it is very easy to grab it and cache it, thus adding an additional layer of caching using the WordPress Object Cache.

Why would you need this if you are already using W3TC or using a hosting company like WPEngine. Both give you various tools for page caching … why use another?

Well, first this plugin is not about replacing your existing caching, but instead making sure that you have adequate caching at the theme level. Even with system level caching there are going to be times where the cache is not served … either because a user is logged in, or because you are getting a lot of traffic and the cache is just missing, or because the cache was purposefully cleared.

ThesisCache(r) just gives you another layer to prevent consuming MySQL/PHP memory if you don’t have too. It gives you page-by-page,post-by-post control over whether to cache a post (or any post type). You can choose to NOT cache a page … or you can even choose to NOT cache the sidebars even though you want to cache the rest.

If you are not currently using ANY object caching no worries, ThesisCache(r) will set up a file-based object cache for you. If you are using an object cache, it will simply leverage what already use.

ThesisCache(r) isn’t in the Plugin Repo yet so here’s the download link. Please report any issues you have in the comments below. I’ll try to deal with them when I can.

So for these clients it’s often a little confusing to have “Posts” at the top of the nav menu. Here’s how you would reorder to the nav to put pages on top.

First turn on the custom ordering option:

add_filter('custom_menu_order','__return_true');

Then create a function to filter the menu order array. In the function below we’re using array_splice to cut out the menu starting at position 2 because the “posts” menu item is #3 by default. How did I know that? Just add print_r($menu) and you’ll get a dump of the menu order. After splicing the array, we iterate over the old menu array, the part we extracted ($old), using a foreach loop adding the old menu items back in.

function mc_menu_order($menu) {
// more on array_splice here: http://php.net/manual/en/function.array-splice.php
	$old = array_splice($menu,2,count($menu),array('2'=>'edit.php?post_type=page'));
	$keys = array_flip($menu);
	foreach($old as $item) {
		if(!array_key_exists($item,$keys)) {
			$menu[] = $item;
		}
	}
	unset($old);
	unset($keys);
	return $menu;
}

Then just add the api call to insert that function:

add_filter('menu_order','mc_menu_order');

Here it is all together:

//menu reorder
add_filter('custom_menu_order','__return_true');
add_filter('menu_order','mc_menu_order');
function mc_menu_order($menu) {
	$old = array_splice($menu,2,count($menu),array('2'=>'edit.php?post_type=page'));
	$keys = array_flip($menu);
	foreach($old as $item) {
		if(!array_key_exists($item,$keys)) {
			$menu[] = $item;
		}
	}
	unset($old);
	unset($keys);
	return $menu;
}
