Hi, appreciate the suggestion but…

From the docs:

"Devel::NYTProf is not currently thread safe or multiplicity safe. If you'd be interested in helping to fix that then please get in touch with us. Meanwhile, profiling is disabled when a thread is created, and NYTProf tries to ignore any activity from perl interpreters other than the first one that loaded it."

So, - not really any help there I'm afraid. This application cannot be run - or rewritten to run - without threads. By definition it runs with over 100 threads and already takes a lot of shortcuts, e.g. to reduce memory footprint per thread for example like doing dynamic module unloading in each thread after startup - which will confuse profiling. To run the program without threads (even if that were possible which it isn't -would take several months development effort to rewrite), it would then take 10s of hours to run the data.

Kind regards

Derek
