Attempting to answer this question directly: if the data you are returning is exactly the same each time, you can send cache control / expires headers with your AJAX response so that the browser knows not to request again for a while. // ask the browser to cache this response, to reduce requests $expires = … Read more
This is really a server question and not particularly WordPress. You’re running into a MySQL server speed bottleneck at 1and1. Sorry, but they’re well known as a slow shared host, and for that reason I doubt their VPSs are any better. Caching and a CDN will only do so much for you. You need more … Read more
To check if the query itself is slow or anything else slows it down, try running your query directly in the database, and have a look at how long it takes there. <?php echo $GLOBALS[‘wp_query’]->request; ?> This shows you the latest Query that WordPress ran in your database. If the query is really slow in … Read more
As I’ve found, this happens when your html, css or javascript tries to load a resource and you haven’t specified a path or wrongly specified root. For instance, I’ve seen examples on people having this problem while doing <img src=”http://example.com” /> background:url(); In my case specifically, was assigning $.ajax() to a global variable so I … Read more
Persuming “article_datetime” to be a numeric value, I would suggest that instead of using ‘orderby’ => ‘meta_value’ use ‘orderby’ => ‘meta_value_num’ If still query is slow, than remove: ‘orderby’ => ‘meta_value’, ‘meta_key’ => ‘article_datetime’, ‘order’ => ‘DESC’ and instead sort the result in php.

Try disabling all plugins first, and set the theme to one of the default themes. Updating your site, plugins and themes could help you as well. Try … Read more

Try this link: WordPress Support It suggests these 7 steps about half way down: Manually run /wp-admin/upgrade.php (visit it in your browser). Try decativating all plugins. If that resolves the issue, reactivate each one individually until you find the cause. Try switching to the Twenty Ten theme to rule-out a theme-specific issue. Download WordPress again … Read more
They’re both doing the same thing. If you don’t pass a post ID, get_the_title() will just use the current post and go about it’s business. The performance difference between passing a postID and not passing a postID is, if anything at all, is extremely minor. get_the_title() Codex get_the_title() Core Function
You can get rid of most of your code above. WP_User_Query has an include parameter (introduced in WordPress 3.9) include (array) – List of users to be included.
