Hi Alex, No, I haven't tried C nor Go. The node and v8 API are exposed in C++. Developing with other languages is trickier (http://stackoverflow.com/questions/12088937/is-it-possible-to-write-node-js-addons-in-go). Why C or Go?
If your concern is speed, I think that the next step is not to change language but to hook directly into v8's internals instead of going through v8's public APIs. This is how JSON.parse is implemented. I measured the total time spent in the public v8 materialization calls (creating strings, objects and arrays) and this time alone is equivalent to the total time used by JSON.parse.
