Drupal hosting

CPU Throttling has caused my client's Drupal website to respond very slowly to the point of disabling it occasionally. This website has only moderate traffic and overall moderate activity. My client is an author and publishes several articles every couple days.

But he chose to host his website at Bluehost using low cost shared hosting. And then he contacted me for help when he couldn't save the articles he had just written. The server was just too busy.
