I agree. Both CPU and BW usage is higher on PhProxy. It is faster though.PHPproxy is the highest one I'd say.
well then why develope two?
Isn't both of the proxies written in different programing languages. One written in CGI/Perl and the other in PHP.
I may be wrong, but that could be the reason for having both as some web hosts does not support php and then some may not support CGI/Perl.
I could be wrong though.
