Luna was our early prototype and it indeed had significant performance problems. Our new JIT compiler is able to execute the graphs really fast (in fact, in many cases we are up to 80x faster than Python nowadays: https://github.com/enso-org/benchmarks).

However, sometimes we see that the WebGL is super-slow on some machines. May I ask you for more details, please? The important bits would be whether you experience the slowdown when using the IDE (like dragging, zooming) or when waiting for data to be computed? In both cases, we would be more than thankful for an issue containing machine spec: https://github.com/enso-org/enso/issues .

Enso should work for you with the same visual performance as in this video (this was recorded on a few years old MacBook Pro): https://youtu.be/fQvWMoOjmQk . If its not this smooth, we need to investigate it, because this is something system / machine specific.

There is unfortunately no other way for us to improve and progress from alpha to beta, so we will be very thankful for help here! <3
