If you've been using it on linux, you've almost certainly already been using the kernel version. Anecdotally, using it on my home LAN, the kernel implementation on linux performs much better than the userland implementation on MacOS. (Admittedly not the same hardware, the linux machine is a i5-3427U while the MacOS machine has an i5-5250U. I think the former might have an L2 cache advantage, but I'm not sure if that would explain the difference.)
