I want to parallelize a code written in Perl. The code loops through multiple files and calls a subroutine for each file. I also need to share some readonly local data-structures with the subroutine.

   sub process_in_parallel {
      my $readOnlySchema = foo();
      foreach my $file (@files) {
          validate_the_file($file,$readOnlySchema);
      }
   }

I am pretty new to perl programming and hence need a lot of advice here. What are the perl modules that the perl monks can recommend for this scenario?

I tried some of the following:

- threads : The problem with this is managing the threads. Is there an efficient thread Manager or thread pool library that can help me with this? I am also not sure if I can share the readOnly object easily.

-Parallel::ForkManager : The problem with this is that it forks processes rather than threads and is increasing the time of execution in my case.

Can you please suggest other libraries also?
