Compression
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 JSSwebcenter.net 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).
