If you use YSlow Firefox toolbar, by now you should have a decent idea about why your website is slow or what you can do to get it up to speed. Here is a quick list of how to solve some of the problem that YSlow points out and others that I find useful.
1. Add Expires Headers
You need to set the expires headers in your .htaccess file in your web root or htdocs directory. For the beginners here is what I would suggest you to use:
2. Disable FileETag is you don't use it
ETag (entity tag) is an HTTP response header returned by an HTTP/1.1 compliant web server used to determine change in content at a given URL. ETags were added to provide a mechanism for validating entities that is more flexible than the last-modified date but If you’re not taking advantage of the flexible validation model that ETags provide, it’s better to just remove the ETag altogether. Removing the ETag reduces the size of the HTTP headers in the response and subsequent requests thus improving site performance.
Add the following to your .htaccess file to remove ETags:
3. Compress components with GZip
Compressing the content (html, js and css), is an important step in optimizing the performance of your site. Depending on the amount of content you have on your site, at a minimum it should give at least 10% improvement in speed.
The code below needs to be added to the .htaccess file in your docroot.
