One of my client faced issue with Autor drop down which is in Admin section.
Display the authors in dropdown menu using hooks.
While creating the New post there was problem with the Author field. There are hundreds of irrelevant selections (users) and it’s difficult to select the right one.
WordPress is by default showing all the users in author drop down. I don’t want to show the other users in author drop down.
Hook/Filter – In wordpress Admin -Add new Post section -Display the authors in a dropdown menu using wp_dropdown_users One of my client faced issue with Autor drop down which is in Admin section. Display the authors in a dropdown menu using hooks
I searched for wp_dropdown_users hook or filter. But I did not found any proper solution.
Following articles are found helpful to me.
http://wordpress.org/support/topic/filter-for-post-quick-edit-author-drop-down
http://codex.wordpress.org/Function_Reference/wp_dropdown_users
Using that code I modified the code and I am able to fix the issue. You can put following code in to functions.php file.
/*
* Hook for showing Admin and Author in Add new Post - Admin section dropdown menu
*/
function wpapi_override_wp_dropdown_users($output) {
global $post, $user_ID;
//get the Admin-role users IDs
$admins = getUsersWithRole('admin');
//get the author-role users IDs
$authors = getUsersWithRole('author');
//merge the array
$result = array_merge($admins, $authors);
//array converted into comma seprated string
$authorsall = implode(",", $result);
// return if this isn't the theme author override dropdown
if (!preg_match('/post_author_override/', $output))
return $output;
// return if we've already replaced the list (end recursion)
if (preg_match('/post_author_override_replaced/', $output))
return $output;
// replacement call to wp_dropdown_users
$output = wp_dropdown_users(array(
'echo' => 0,
'name' => 'post_author_override_replaced',
'selected' => empty($post->ID) ? $user_ID : $post->post_author,
'include_selected' => true,
'include' => $authorsall
));
// put the original name back
$output = preg_replace('/post_author_override_replaced/', 'post_author_override', $output);
return $output;
}
add_filter('wp_dropdown_users', 'wpapi_override_wp_dropdown_users');
/*
* Find User IDs by Role
*/
function getUsersWithRole($role) {
$wp_user_search = new WP_User_Search($usersearch, $userspage, $role);
return $wp_user_search->get_results();
}
Using above code, you can load multiple role users in author drop down.

Using social button will slow down your wordpress site
But these plugin can cause wild swings in page load times and page load. Sometimes, facebook is busy and that icon slows down your page, sometimes it is twitter.
Some time admin selected so many social icons to show and it takes time to load because that many apache requests will go to server. I personally tested some blogs and They are facing same page load issue. Commonly wordpress page will load in 5 to 6 seconds without this wordpess plugin. But with these plugin it is taking 50 to 60 seconds to load the page.
It will affect to SEO of your site.
Our Test
We tested the following social icons buttons.
Twitter, Twitter (tweet), Facebook, Facebook (like), Delicious, Google Bookmarks, Google Reader, Google email, Posterous, and StumbleUpon.

Social buttons attract more visitors to your site. When users +1, Tweet, or Like your page, it advertises your page to their friends and followers. This plugin adds social buttons to your posts as a small sprite at first and delays loading the real buttons until the user hovers over the social buttons. It delays ~300KB of social button components by loading <6.5KB of our own script and sprite. onMouseOver activates the load of the ~300KB of social button components.
No one likes long load times, but we all want to be able to share our content via Facebook, Twitter, and other social networks. These take a long time to load. Paradox? Not anymore! With WPSocialite (utilizing David Bushell’s amazing SocialiteJS plugin [http://www.socialitejs.com/]) we can manage the loading process of our social sharing links.

If you want to disable post revision system permanently, you can add following line in wp_config.php file.
define('WP_POST_REVISIONS', false);
But it has some bad issues also. If you have 5 to 10 revision per post and 200 posts then you will have at least 1500 to 2000 entries in table. Most important part is all revisions are unuseful. Each additional revision increase the size of your database thus making the processing time slower and slower.

For cleaning the database you can use the following plugins.
This plugin is a ‘One Click’ WordPress Database Cleaner / Optimizer.
