Yeah, that is not something i am sure about is memory management. Perl is my first language and so far it is the only language i use. The significant slowdown can be fized by usung a small value as a read length, but that does not output fast enough. There is still alot i am not completely positive about, like when you says "your stack will fill up", do you mean the memory?

As for the logic it is pretty straight forward (or what i thought was ;) ), the iterator is what actually sets the size in which you want to split the file, so doubling it will actual make it split the file into 4gb chunks, and once the iterator hits its mark, it calls the sub again, until $buf != read length (which was the only way i knew of to check for eof.)

If you set the iterator to a higher value you ofcourse need to adjust the read length of $buf. With that said, What would be a better way to check $buf for end of file? And thanks for pointing all this out to me :)
