Perlbeginner1,

Only you know what size machine you need. I have never used 'Parallel::ForkManager', but I have used 'fork' on a lot of different *nix machines. So I'll give you some ideas to look at:

• What does 'top' tell you when you run (1..10) scripts.
• How are you connected to the Internet. If you don't have enough bandwidth you can add 1024 cores and it won't help.
• How often do you have to check the URLs? Too often and you may be bounced by the URL's admins.

I've found that adding more than 4 forks per core starts slowing things down. But only you will know that after testing current performance.

Now if you really want that new 4-core machine, and you want our premission, then I'm all for it :-)

Good Luck!
