That depends.
If you’re using Bluehost, Godaddy, Hostgator, A Small Orange or any other EIG owned company you’ll probably need to move to get your site loading super fast. The only way cheap companies make any money on those $3-5/month hosting plans is to stack 10,000 other websites on the same server and run the server as hard as possible.
We find that we can get sites running on these services down to a passable 3-5 second load time BUT the site will struggle to handle more than a handful of simultaneous users at a time.
When it comes to hosting you get what you pay for – it’s unreasonable to expect a high quality service when you pay more for a coffee than you do for an entire month of hosting or 1-2 clicks on your Adwords or Facebook ads.
Typically we’ll recommend these 3 options for customers on a poor quality web host:
WPX Hosting
WP Engine Hosting
WP Alpha – our Australian-Based, Managed WordPress Solution
