Cons

Con
Arcane configuration format

Configuration is as good as the manuals go. As soon as you have to configure it by yourself, it becomes a lot more difficult due to a rather obtuse system of configuration with long and confusing variable names, which has become infamous among web developers.

Con
Process Based Request Handling

Each request opens a new process/fork to handle just that request (ver memory inefficient)

Con
Extremely inneficient

Opens a new thread for each request. In practice this means that unless you use a proxy (nginx) you can only have a certain number of people on your site at a time, and is extremely inefficient on the server side.
