[edit] About

Distcc is a program for distributed compiling. It sends preprocessed C code across a network so it can be compiled on other machines, the other machine then sends the object file back.

This can produce a noticeable speedup on slow machines, however it will not help with the ./configure (GNU Autotools) stage, or the linking stage.

[edit] Security

Distcc allows arbitrary commands to be run as the distcc user. If you feel this is to much of a security hole then don't run distccd. In order to secure it properly you should probably be running distccd with something like --allow 137.112.0.0/16 which will restrict access to the Rose-Hulman network. You should also make sure that it is running as an unprivileged user.
