Well, not really a patch but a tiny contribution to an excellent guide -- Mr Beckman, I hope this is of use:
On/section: guide/performance.html#Using_1_Under_mod_perl_and_be "Using $|=1 Under mod_perl and Better print() Techniques" Whilst the code is correct, even if it does use CGI.pm..., It might be a good idea to mention that if an external file is pulled in by the header, it seems that it has to be loaded before any output occurs. My print_html_header methods have a flag which will cause SCRIPT src and relevant LINK href URIs to be parsed, loaded and included inline. Slow but better than a poke in the eye with a sharp stick. Hope that helps lee
