slow page loading

Hi, I am building a resource planning instrument and I have some performance issues when I try to load 3/400 hundred steps at the same time.
Is there any plan to support lazy loading on scrolls?

I'm facing the same issue with about 185 steps. From my perspective the issue seems to be related to dom element rendering.

We are facing the same issue when loading several hundred steps in a gantt chart.
Until everything is loaded, Chrome spends more than 20 seconds and Firefox about 40 seconds.

Do you have any idea why Firefox takes so much more time? And is there any possibility to improve the loading times for the gantt component?

For example, it seems that adding a (sub)step always triggers recalculation of the gantt boundaries. Are there any options for adding several (sub)steps at the same time to reduce the loading time?
