Apache's mod_fastcgi makes Perl applications run much faster and scale well to heavy usage. Using Kwiki with mod_fastcgi is a piece of cake.

First you need is an Apache server built with mod_fstcgi support. See http://www.fastcgi.com/ for more information.

Then install a Kwiki site following the normal Kwiki Installation procedures.

Finally add something like this to your Apache configuration (The example is for named virtual host):

<VirtualHost *>
  ServerName kwiki.yourhost.name
  DocumentRoot /usr/local/www/data/kwiki

  AddHandler fastcgi-script cgi
  DirectoryIndex index.cgi

  <Location />
    Options ExecCGI
  </Location>
</VirtualHost>

That's it! You'll get an instant performance boost.

You can switch from the standard CGI installation to mod_fastcgi anytime you want.
