Docker on FreeBSD Docker is a popular container tool and ecosystem, comparable to FreeBSD Container & Jail tools, used to simplify and speed-up the creation, deployment and management of isolated application environments. Docker Homepage Work is currently in-progress to develop a FreeBSD Containers: Jail runtime implementation ("runj") and FreeBSD OCI Container Specification necessary to integrate

Comparing mutiqueue support Linux vs FreeBSD Written by Takuya ASADA<[email protected]> After I joined Network BoF, I realized maybe it's good to share my knowledge of Linux network stack implementation. Because Linux has some more "generic" APIs / features which FreeBSD doesn't have today. So I wrote this. I hope it helps to think what kind of interfaces/features we need on FreeBSD. RPS (Receive P

netmap is a framework for high speed packet I/O. Together with its companion VALE software switch, it is implemented as a single kernel module and available for FreeBSD, Linux and now also Windows (OSX still missing, unfortunately). netmap supports access to network cards (NICs), host stack, virtual ports (the "VALE" switch), and "netmap pipes". It can easily reach line rate on 10G NICs (14.88Â Mpp
