Actually, there is a slight performance hit, but it isn't much.
PHP will by default buffer the output, But this is not a huge buffer(I
forget the size),and when it fills, the output is sent to the web server.
If you use output buffering, all the output is buffered until you send
the data on. This will generally require more RAM for the larger
buffer, and more CPU cycles to process the buffer.
But it's not a great amount unless you have large pages.
