in reply to calculate the time taken to run a script

Another method is if you are running a Linux environment and the CGI is executable from the command line, you can see the raw time (with no code changes) using the time bash command:

#~> time ./some_script.(pl|cgi)
Outputs:
real 0m0.000s user 0m0.000s sys 0m0.000s
Always a very simple and quick method of timing different utilities and things like that.
