Oh you meant cgi.  CGI should be reserved for CGI.pm stuff.

I don't use CGI's html functions at all because I just
don't see much saving in terms of typing.  I guess I am 
in between your 'RAW' case and CGI.pm case

I only use CGI's param,header,cookie and redirect functions 
and DISABLE_UPLOADS and POST_MAX variables.  Given that
real handler is the second best performer after static
html I wonder how big of a step from using Registry to 
writing a handler. I know I can rely on CGI because
it is time tested. I wonder whether there are CGI equivalent
modules if I don't use handler.  I read earlier
that CGI alternatives have some problems.

It's documentated and benchmarked in the guide:
http://perl.apache.org/guide/performance.html#Object_Methods_Calls_vs_Functio
http://perl.apache.org/guide/performance.html#Are_All_Methods_Slower_than_Func

IIRC, CGI.pm is actually slower to run the functional syntax than the object
syntax. This is because accessing CGI's functions end up getting dispatched
through a complex autoload(ish) mechanism.

I haven't benchmarked this though, so it's only theory!

See http://www.chamas.com/bench/#perlcgi

The Raw CGI test makes no use of CGI.pm, just issues raw print 
statements that sets up the right CGI headers.  Please note that the 
number that I reported showed a difference of .00065 seconds of system 
time per request between CGI.pm & Raw CGI HelloWorld, so I wouldn't much 
worry about the environment overhead.

If you are using CGI.pm object methods, I would worry about calling 
all those methods to build your HTML and if you are performance 
minded, I would use them frugally.

Could you please explain the differences between
CGI Raw and CGI.pm?  I'm using oo method of
CGI.

Thanks
