KwikiFastCGI
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 KwikiInstallation 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.
