What is zlib?
zlib is a lossless data-compression library built into PHP.
Page compression is commonly used to achieve faster page load times and reduce bandwidth usage. Compressed pages use less data, thus reducing how much time it takes for a visitor to load a page. Likewise, if less data is being transferred to the visitor, your server does not need to use as much bandwidth.
Plus, since zlib is lossless, compression should not affect your site visually.
