Hi folks,
I am testing a web page by using some modules from cpan, such as
SSLeay, WWW::Mechanize,etc. On top, I am using threads to simulated
more than multiple users.
During the run-time, if I was to simulate one or tens' of users to
access that web page, all my scripts runs smoothingly without a single
error.
However, when I was to simulate couple of hundreds of users to access
that web page, I am seeing these kind of results coming from:
1. Sometimes it gives messages as that "it can not find a certain form
on a certain page", which not suppose to be.
2. Sometimes there is a "Segmentation fault"
Why I get those messages, is that because of the script I am running,
or the modules being used, or it is a really problem when too many
users are accessing that web page at the same time ?
Any tips, suggestions ?
Thanks for the help
CJ

Could be any one of the above. As you state in your first paragraph,
your overall program design is quite complex. Perhaps you should take
it apart, start with the first component, and test each component as
you add to it. The problem may be a Perl problem -- or it may not.
BTW, it's not at all clear what you mean by "testing a web page by
using some modules from cpan".
