The HTML page should be transferred using GZip compression.
The X-powered header is sent within the response header. (unnecessary)
Performance
(Somewhat important)
The page response time of 0.93 seconds is longer than the recommended limit of 0.4 seconds. A high response time unnecessarily slows down search engine crawling and results in bad user experience as well.
