The second method we use to boost our server performance is mod_gzip, a compression module which uses the standard zlib compression library to compress output. The idea is to compress data being sent out from the Web server, and have the browser decompress this data on the fly, thus reducing the amount of data sent and increasing the page display speed. Using HTTP compression, a performance gain of 150-160% is achieved across all ImHosted.com web servers. Using HTTP Compression web pages can be 90% or so smaller and images can be up to 50% or so smaller (depending on how much they are compressed already).More information about HTTP compression can be found here.
