generally speaking, general questions got general answers: specific questions have more change to get good quality answers.

That said I have to admit I have no such big experience with threaded application, but I have experience with monastery, so I can provide my little help, but remember Super Search is your friend!

What I have learned reading other monks's posts is that writing good quality Perl multithread program is not easy. But not impossible. Many monks here around are able to do it. Among them i warmly suggest posts by BrowserUk zentara marioroy NetWallah and also some practicing one like karlgoethbier. Search their posts and you'll find tresaures!.

While BrowserUk write his softwere using standard Perl modules marioroy has developped his own module MCE that seems very interesting and probably, easier to adopt solution. MCE::Loop if i recall correctly is aimed to process in parallel large files

Some useful reads are: Help me beat NodeJS and Fast provider feeding slow consumer but you can find more in my confusionary homenode.
