Was your timing fair? Did you start all the programs with clear buffers on both sides? The best way to make sure there are no favourful buffers is to reboot both machines before doing each test. Furthermore, the network could have been the bottleneck - have to make sure you performed the test on a quiet network?

I find it hard to believe cp would be 2.5 times slower than File::Copy.
