Hello hveneticus,

Welcome to wonderful world of Perl. your question in not that much related to Perl. I would recommend to you to take a look on the Perl module Net::OpenSSH::Parallel.

With this module you can create parallel ssh connections apply your commands and collect the data in parallel. How? Glad you ask, here are some examples that I have done for related questions Net::OpenSSH::Parallel with sudo commands, multiple machines disk space alert and Best module to execute administrator commands on external operating systems (Linux).

Hope this helps.
