Before describing the manipulation to be done to accelerate the speed of your site and reduce loading times, we want to clarify that some of these tips work well for sites that are not under WordPress.
Google said that the speed of page loading was a factor to consider in the SEO, then we should better optimize it.
Open to edit your .Htaccess file (take a backup first). For us, using online FTP works great to do the job. Add the following codes to your .Htaccess file before the starting of your WordPress rewrite rules:

You can read this interesting and useful topic to optimize the pageload speed from Yahoo. It really nicely written. You can implement PHP buffer flush to load very quickly.

//<?php flush(); ?> |

Yes, these are basics and will work forever for Apache web server.
Thank you for your quick reply, how about on a light speed server?
Since LiteSpeed claims to have compatibility with Apache, it should work. LiteSpeed will follow `mod_rewrite` rules the same way as Apache2.
