Performance schematic editor very poor

Tim Numan

A bigger project with 16x8 buttons/leds and diodes performs very poorly on my 2019 macbook pro. intel i9 8 core 2.4ghz with 32gb ram.

3d viewer is ok once it loads, schematic is very bad. On Chrome it's unresponsive, in firefox it's responsive but still very slow.

Thanks Tim Numan for the helpful report. I'm wanting to get a bit more info on which specific interactions are causing the unresponsive behaviour.
I'm not getting outright unresponsive behaviour in Chrome myself on the linked project (similarish machine specs) -- although I am still seeing some real perf issues which we'll want to address. 
I'd like to be sure we're looking at the same thing though.
Would you be willing to make a short screen recording of the worst-performing interactions (and steps leading up to them, if any)? Eg using loom.com

Bryan Hoyt Hey Bryan, thanks for the reply. I saw a support cursor looking at the project quite quick after I submitted the report and after that the schematic editor performed a bit better. The pcb view is terrible though, I have to turn off as many layers as I can and then I can click around, maybe connect two points and after that it needs to load/render for a long time before I see a result.
I'm a web app dev myself and one thing I noticed is that everything stalls (also text inputs are pretty much unresponsive) and that you use MUI components. MUI text inputs are terrible slow and cause many issues in my web apps. Any render issues you have are magnified because of these inputs. I have in the past used native inputs with MUI styling and rendering speeds greatly improved.
I'm gonna make a video and add it here �

Now the PCB 2d and 3d view aren't loading at all.. not even for simple new projects..
