Hi, i am using perl from last one year and looking for some help in this forum. I have a webapplication on which i have to perform stress load and performance testing. So i did a little investigation and was able to use LWP::UserAgent, HTTP::Request::Common qw(POST and HTTP::Cookies modules to talk to my webserver and get all the information. I want to know, is it possible to create multiple threads which simultaneously post's requests to the webserver. Is it better to use open source tools ? The requirement is 1. 1 user request. The response time should not exceed 1 minute. 2. 50 user requesting. The response time should not exceed 1 minute. Also all the 50 responses should have the same content. 3. 100 user and so on. I am not able to judge if using perl will I be able to complete the above requirements. Also if i use threads will all the threads requests the webserver at the same timeline.
