Re: Using threads with Ping

A very informative node on threads (++ to all).

Am I just being too sarcastic to see the value in spawning of a bunch of threads that just do a backtick operation? Don't get me wrong, I see the general value in the question and answers about thread spawning and joining but would this be a proper monks node without someone questioning the given script. Is there something funky about perl on Win32 that I'm missing (like backticks don't fork/exec). Or more general, is there any value in spawing threads that will just fork/exec a cmd.

My first inclination is that no, there is no value in that. You should either junk the thread overhead and just stick with fork/exec (and not use backticks because there's overhead in that with a shell coming into the equation) or find some "thread-safe/thread-aware" way to ping (is Net::Ping thread-safe?).

However, if this is just an exercise in threading and is not going to be used in the real world - then nevermind.

It was an exercise and I plan on using it in the real world. I use this in a CGI based interface. Net::Ping has to run as someone with Administrator on IIS which was not allowed.(Yes I even tried commenting out that line...) I read that using threads was much more memory efficent than using fork. I am not qualified to debate you on which method is faster or more efficent, or better (fork/threads). Why don't you post that question to the Monks?	[reply]
