If your 5.8.9 is 32-bit and 5.10.0 is 64-bit, then you can expect data structures to use more memory, up to twice as much in the worst case. -- David Cantrell | Nth greatest programmer in the world Hail Caesar!

Re: Perl 5.10.0 Memory Usage
I found some circular references, and after removing them, garbage collection worked as expected. Strange that Perl 5.8.9 destroyed the objects, but Perl 5.10.0 didn't. Is there an easy way to troubleshoot this sort of problem, other than digging through your code? I recently upgraded from Leopard to Snow Leopard. Now, some scripts that ran nicely on Perl 5.8.9 are consuming all available RAM on Perl 5.10.0, and bringing the system to its knees. The scripts I'm referring to create a series of large objects, each of which should be garbage-collected when the next object is created. Apparently, Perl 5.10.0 is not picking up the trash.
