body: <p>Can someone tell me the difference in the following scripts in terms of CPU load performance and compression?</p>
  
  <pre><code>&lt;ifModule mod_gzip.c&gt; 
  mod_gzip_on Yes 
  mod_gzip_dechunk Yes 
  mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$ 
  mod_gzip_item_include handler ^cgi-script$ mod_gzip_item_include mime ^text/.* 
  mod_gzip_item_include mime ^application/x-javascript.* 
  mod_gzip_item_exclude mime ^image/.* 
  mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.* 
  &lt;/ifModule&gt; 
  
  
  &lt;ifModule mod_deflate.c&gt; 
  &lt;filesMatch "\.(js|css)$"&gt; SetOutputFilter DEFLATE &lt;/filesMatch&gt; 
  &lt;/ifModule&gt; 
  </code></pre>
