Recently I gave an one hour webinar to help developers to prepare for a hackathon related to IBM Watson IoT. I demonstrated Node-RED and coded live some sample flows.

Over the last month or so, I’ve been working on an application that pushes performance quite a bit. Last week I published a blog post about aspects of developing for performance. I’ll be writing a future blog post (maybe more than one) on the approaches I’ve taken for performance. But in this blog post I want to take a step back and discuss why I had to address performance, even after quite a bit of optimisation from the initial development.
