If you're looking to get in to instant notifications without suffering from backlog, I'd looking in to both Node.js and Socket.io. You should be able to work with them both pretty easily and integrate w/ WordPress. The sample chat application on the Socket.io site isn't a far cry from what you'd be doing. Basically an event is triggered on your LAMP/LNMP ...
The Transients API is similar to the Options API and that means as of right now, unless they make a change in v4.1 or the future release, all of your transients are going to be moving in and out of the tableprefix_options table.

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.
After almost 4 years I got back on this and finally found the problem. Turns out the site had a lot of articles ALL marked as sticky. Due to the unbelievably dumb way wordpress uses to mark sticky posts (a serialized array in wp_options), the main loop of the dynamic home page took an incredibly long time. Clearing the sticky_posts field in the table fixed ...
