Description
I ran the render.py code for generating multi view images, but I found it is stucked.
So I ran the render.py mannually, and I find the render engine for CYCLE takes very long time (10 mins):

Is there any methods to run the blender rendering quicker?

Research direction
Start with dataset_toolkits/blender_script/render.py and reproduce the command shown in the issue using Blender 3.0.1 with the CYCLES engine. Use the log to investigate the delay during render-kernel loading and scene updates. Done means identifying and addressing the cause of the excessive render time, with a faster rendering result for the reported command.
