Plugin 2:  HTML Compression:

This plugin compresses your blog pages in gzip format. If a browser supports HTTP compression then this plugin will work. It reduces size of the page by 60-7-% and hence increases loading speed of website by 3-4 times. Gzip compression may not be supported by your blog if it’s not updated to latest version.  You need to upgrade your blog to updated version in order to get gzip compression functionality. You can easily test your blog using a simple tool at Is My Blog Working?

If you’re not using the latest version of WordPress, you may not be able to use the gzip compression. Test your blog using the simple tool at Is My Blog Working?
NOTE: I won’t recommend this plugin to those who are using WP Super Cache, as it uses compression functionality so WP Super cache will stop caching new pages.
