Is Web Compression effective for improving page load speed?

I guess you are referring to HTTP compression which is recommended for websites to improve the download time. This web compression method is also referred to as content encoding. It is a publicly defined method of compressing textual content that is transmitted from web servers into web browsers. This method of compression uses public domain compression algorithms such as compress and GZIP to be able to compress XHTML, JavaScript, CSS, and other text files in the server.

This standard-based technique of providing compressed content is integrated into HTTP 1.1 and nearly all modern web browsers that support HTTP 1.1 has support for ZLIB inflation of deflated contents or documents. This means, they can automatically decompress compressed files which in turn saves time especially bandwidth. On average, based on the tests conducted, web compression is able to decrease the size of the text files to one-fourth or 25 percent [25%] of their original size.

I guess this means, the more texts you have on your website or web server, the greater the savings.
