slowcgi is a server which implements the FastCGI Protocol to execute CGI scripts. FastCGI was designed to overcome the CGI protocol's scalability and resource sharing limitations. While CGI scripts need to be forked for every request, FastCGI scripts can be kept running and handle many HTTP requests.
slowcgi is a simple server that translates FastCGI requests to the CGI protocol. It executes the requested CGI script and translates its output back to the FastCGI protocol.
Modern web frameworks and web applications usually come with the capability to run as FastCGI servers. slowcgi is not intended for these applications.
slowcgi opens a socket at /var/www/run/slowcgi.sock, owned by www:www, with permissions 0660. It will then chroot(8) to /var/www and drop privileges to user “www”.
The options are as follows:
 
 
Do not daemonize. If this option is specified, slowcgi will run in the foreground and log to stderr.
 
 
path
chroot(2) to path. A path of / effectively disables the chroot.
 
 
socket
Create and bind to alternative local socket at socket.
 
 
user
Drop privileges to user instead of default user www and chroot(8) to the home directory of user.

The slowcgi server first appeared in OpenBSD 5.4.

slowcgi only implements the parts of the FastCGI standard needed to execute CGI scripts. This is intentional.
