I havent heard anything more about node being ported to use chakra - I think they were targeting a pr by summer, is that still happening? Would love to see some of this performance competition on the server side as well.
Edit: looks like the pr ran into some opposition but im not sure what the final status is, ill have to read it again later when im not on mobile. https://github.com/nodejs/node/pull/4765

So yes, for now Node-ChakraCore repo is accepted as part of the Node.js foundation and is being kept up to date with the master. We are also collaborating with several Node core members in order to carefully understand and plan the best way to bring it to the mainline. This effort is called VM Neutrality (or Multi-VM) for Node. You can find out more about this here https://github.com/nodejs/vm
This definitely seems neat, but is it really necessary?
If you're doing CPU bound tasks with Node in the first place, you're doing something wrong. I can't see the tiny edge in performance being worthwhile for the headaches it may cause.
