我安装了Firefox Pluggin yslow以在我的网站上获得反馈。由于在论坛推荐的改变，我得分了91个，这是一个评分。
I have read many articles on improving the page load for Drupal and used as many steps as possible to enhance the speed of the site.
I installed the FireFox pluggin YSlow to get feedback on my site. I scored a 91 with an A rating thanks to the changes recommended in the forum.
YSlow is giving me an Grade F on Configure entity tags (ETags) and Grade F on Use cookie-free domains.
Are ETags and Cookie-Free domains, something I should concern myself with?
Even though I have a good rating, I still feel the home page loads slowly. Even going from a page with images to a text only page there is a delay.
If your using multiple web servers then ETags need to be configured correctly. Add this to your .htaccess file (at the bottom) if this is the case. If you only have 1 server then you can safely ignore this recommendation.

Cookie-free domains offer a slight performance improvement because less data will be traveling over the wire. You need a CDN to get a cookie-free domain setup correctly.
