Huh?

Believe it or not, WordPress doesn't have a fully-fleshed out common tab style for plugins or theme authors to use in metaboxes.

The style exists for categories, but it hasn't been fully adapted for the half-complete wp-tab setup. Trac ticket #17959 has a solution that not only fleshes the style but it also adds a global JavaScript file to give the wp-tab HTML some action. Until that ticket is accepted into core, this Gist adapts that code so it's available to use independently in your theme or plugin.

How?

Just enqueue the CSS and JavaScript in the admin_enqueue_scripts script hook and drop the tab HTML in a metabox. It will automatically adapt to the normal and side column widths, much like category tabs.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

var http = require('http'),
    fs = require('fs'),
    // NEVER use a Sync function except at start-up!
    index = fs.readFileSync(__dirname + '/index.html');

// Send index.html to all requests
var app = http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.end(index);
});
