I don't think the blog post above here is about using julia for ultra-low-latency systems to be pair. 'Production ready' is a pretty vague statement and certainly doesn't apply to every usecase. I'd say that if people have other reasons to use julia in a realtime low-latency production system -- like needing it's scientific stack -- then you can certainly make it work, you just need to do some testing to make sure you're not hitting GC.
