Performance of CGI Reduced

[Praki]

Hi All,

when i use

use CGI;
use CGI::Session;
use Net::LDAP;

in my cgi file the performance is reduced. i mean it takes more time
to get load every time and all the pages where ever i use this .
why it is happening ? is there any other alternative for this...

Thanks,
Prakash

More time than what?
Using those modules means slurping several thousand lines of code into
your program, and yes, that takes some time.

why it is happening ? is there any other alternative for this...

If you are using Apache, have a look at mod_perl http://perl.apache.org/,
which embeds a Perl interpreter in your webserver and caches the
compiled Perl code.

As compared to what? Using none of the above? Using one of the above?
Using two of the above?

mod_perl, for example. See the FAQ "How can I make my CGI script more
efficient?"

You can use part only

use CGI qwcgi);
or
use CGI qwstandard);
or other part you need.

That would import a bunch of symbols, and I don't understand how it
would improve performance.

To the OP: As others have mentioned, you may want to run the program
under mod_perl. Otherwise, as long as you run it as a plain CGI script,
and if speed is an issue, avoid using CGI.pm.

Given that most of the penalty for using CGI.pm comes from having to
load, parse and compile that behemoth, changing the set of imported
routines would, as you point out, not increase performance.

And one very good way to avoid CGI.pm (so long as one does not need the
HTML generation methods) is to use CGI::Minimal:

I would still prefer to go with a CPAN module than home-brew solutions.
