title: Website too slow after using htaccess rewrite rules
body: <p>I recently added a couple rewrite rules and since then my site has been too slow. What will be a more efficient way to use these rewrite rules:</p>
  
  <pre><code>RewriteRule ^videos/([0-9a-zA-Z-]+)$ videos.php?var=$1 [NC,L]
  RewriteRule ^article/([0-9a-zA-Z-]+)$ article.php?var=$1 [NC,L]
  RewriteRule ^video/([0-9a-zA-Z-]+)$ video.php?var=$1 [NC,L]
  </code></pre>
  
  <p>Thanks in advance!</p>
