title: Website down because of account throttling
body: <p>I developed a website using PHP and MySQL. The website is being hosted on Bluehost using their Pro plan. The account contains only the website and a vBulletin forum.
  It goes down because of account throttling.</p>
  
  <p>Average of concurrent users is 80 - 200</p>
  
  <p>The website was stable and fine for 800 concurrent users in the last month,
  but now it's going down for less than 100 users.</p>
  
  <p>Technically I do the following for each page</p>
  
  <ul>
  <li>Execute about 2-5 select queries (using MySQLi)</li>
  <li>I turn on output buffering ( ob_start() )</li>
  <li>Load a template file for HTML output</li>
  <li>Turn off with clean output buffering ( ob_end_clean() )</li>
  <li><p>Get the string output and write it to an external file</p></li>
  <li><p>If the page gets requested again, I get the output from the file, and I am not doing the above steps</p></li>
  </ul>
  
  <p>The average page load time before caching the output (in external file) is about 5-10 seconds. After caching the output time is 2-4 seconds</p>
  
  <p>Although there is no heavy usage of the database, my account has been throttled and goes down sometimes.</p>
  
  <p>When I execute "SHOW PROCESSLIST" I get 1 row result</p>
  
  <p>Can I get an advice for this case</p>
