in reply to Re^2: Perl thread profiler
in thread Perl thread profiler

I suspect from the OPs post, that he is looking for something like this, which is a very powerful tool.

But, whilst I think it could be used to great affect to tune perl's internal implementation of threading; it is not so useful for tuning iThreads user code, as it is a binary level rather than source-code level profiler. Trying to separate out the affects of user code from those of the Perl runtime code is pretty much impossible.

Like you, I also tend to tune my threaded Perl code by isolating each thread as far as possible and then tuning each thread in a stand-alone fashion.

    I am basically looking to get the cpu/memory/blkio usage for each of the different threads in my process. I can get the usage for the process as a whole but that doesnt satisfy my purpose as I want to determine how my threads are effecting the box.
