For me lux is fast everywhere than cycles especially high resolution render.
I'm currently rendering 3k interior for an architect and it is so fast. Yes With PGI of course. I've to adapt a bit my workflow when i feel performance degradation (help the render engine a bit) in a way that give me always the perf i know lux can deliver.

but I'm not comparing with cycles but with e-cycles and octane.

Yes i Know but speed i'm talking about is far from 50% improvement (with PGI). But anyway it is always good to spot area for improvement as you do.
This way we get even faster when proper solution is on track. With my workflow it is hard to spot such kind on under performing scenario i mean.

I think there is some problem with MIS or something. Both octane and ecycles can in very first passes give very detailed shadows and lighting etc, rest is just gi noise, reflections etc.. luxcore can easily take much more time to sample shadow areas or multiple lightsources and some noise stays after thhousands of samples...
