cgi process time

Murcia has asked for the wisdom of the Perl Monks concerning the following question:

Hi Confreres,

I have a CGI script that needs some time to generate the output. I want to follow the process time in the html output the program needs in each module or subroutines to later improve the code.

What is the best way to do so?

Yours

Murcia

Hi Murcia, You should start by reading Watching long process through CGI by merlyn. Also in When Perl is not fast enough Nicholas Clark discusses the use of the Devel::DProf module (along with plenty of other techniques) to find out why things are running slow. Take a look at the article and the module. Hope this helps. Martin	[reply]

You could use the Time module. How you actually use it, is your choice. Here is a generic example: `use Time::Local; my $StartTime = time(); print "Doing nothing but waisting time....\n"; for ($i = 0; $i < 10000000; $i++) { } $EndTime = time(); print "Waisted: ". ($EndTime - $StartTime) ."s\n";` [download]	[reply] [d/l]

granular time is better for web app benchmarking: `use Time::HiRes qw(time); my $bench = time; handle_request(); printf 'Code took %.4f seconds', time - $bench;` [download]	[reply] [d/l]
