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.
