No, but you can make meaningful measurements :)

I think the issue here is actually the OS and filesystem. I'm willing to bet
that OpenServer is doing synchronous writes, and Linux does async. It would
then take the same amount of time to do the data transfer, but the Linux cp
would just return faster. That, and that particular OS isn't well-known for
its blazing speed. :)
