Page Load Speed, Hostgator and Wordpress

[pmeenan]

Yes, VPS is usually also oversold but you can usually "reserve" dedicated capacity (though that is usually CPU and memory - I/O can still be iffy).

Another option to look at is something like EC2 (or other cloud-based VPS systems) where they also account for I/O. The EC2 micro instances can be really affordable and give you all the control in the world (but that does require even more systems management).

Maybe the best option would be to look at a wordpress-specific hosting provider (like wordpress.com but I've also heard good things about Media Temple: http://mediatemple.net/wordpress-webhosting.php )
