I have a working piece of code which performs a series of HTTP GET requests within a second. I am using LWP::Simple module to perform the GET requests and the Time::HiRes to pause for a fraction of a second between requests. The baseline time it takes to perform a GET request to a certain server is 0.06 sec (or 60,000 msec), so i deduced that in order to perform 10 requests a second i must sleep for 0.04 seconds (Actually, to account for any errors I rounded down the sleeping time to 0.03 sec).

The reason I am posting this is to ask if anyone knows of a better or more efficient way to produce a script that "pounds" a server at 'x' times per second.

Thank You very much,

jcr

here is the code:

use LWP::Simple;
use Time::HiRes qw(usleep);

open(URL_LIST, 'url_list.txt') || die "Cannot open: 'url_list'\n$!\n";
while(<URL_LIST>) {

  chomp;

  get($_);

  usleep('0.03');

}

close(URL_LIST);
