It is recommended that you compile and install this small program only if you intend to install and use the Apache web server with third party modules like:
mod_ssl for encrypted data
mod_perl for the Perl programming language
mod_php for the PHP server-side scripting language.
This program will provide a significant performance to Apache modules. For instance if you need to install Apache with SSL support for your electronic commerce on the Internet, this will allows the SSL protocol to use a high-performance RAM-based session cache instead of a disk-based one.
