Hi,

I am working on a requirement to draw a canvas with 300 elements. I am using draw2d "reader.unmarshal" function but entire process is taking up almost 3 minutes to load the canvas completely. Also during the loading of canvas (3 minutes) the CPU usage is 100% and the entire UI becomes unresponsive.

Framework: Angular 10
Draw2d: version 1.0.19 (Also tried with v1.0.38 without success)

Please help me to improve the performance of the application. Thanks in advance.
