WordPress, by default, comes uncompressed and sends the uncompressed HTML to the visitor’s browser. With one line of code added to your header, you can compress WordPress’s output by up to 75%. By using zlib compression technology, you can harness the power of PHP and reduce your blog’s load speed!

First, place the following code in a file and call it "test.php" and then upload it to the root of your blog directory:

<?php phpinfo(); ?>

Make sure that "zlib" is enabled by your hosting provider.

Second, place the following code in your header (above the DOCTYPE):

<?php
ini_set('zlib.output_compression', 'On');
ini_set('zlib.output_compression_level', '1');
?>

You’re done! Check Port80Software.com to ensure you are compressing your output.
