Something must be wrong with the conduit "NoHandle" code. I increased the filesize to 60MB and implemented the copy loop in pure C, the code and results are here:

Everything but the conduit NoHandle code runs in roughly 600-620ms, including the pure C version.

Does your workstation have an SSD? Michael's using a spinning disk.


If you're only copying a GB or so, it should only be memory traffic.
