I don't think I'm good enough to teach others, However, There are some explain I think can help you.

Add an Expires header

Adding an Expires header to your components with a date in the future makes them cacheable, reducing the load time of your pages. Certainly this should be done with images, but that's fairly typical. Go a step further and add it to scripts and stylesheets, too. This won't affect performance the first time users hit your page, but on subsequent page views it could reduce response times by 50% or more.

Gzip componentes

Gzipping all the js and css files types to reduce page weight. The greatest advantage is compressed to reduce the amount of data transmission network, thereby improving the client browser access speed. Of course, but also increase the burden on the server a little bit. Gzip is a more common form of HTTP compression algorithm.

Configure ETags

1. Client requests a page (A).
2. The server Back to A, and A to add a ETag.
3. Client display the page, and pages together with the ETag cache.
4. Customers once again request pages A, and the last request to the server to return to the ETag transmitted to the server.
5. Server checks the ETag, and to determine the page since the last client request has not been modified, to return to direct response to a 304 (Not Modified) and a response of the air.
So. ETag is a Tag to your components to see if they has been modified. If not here will be no request happened. Configure it is a good way.
