What could be the reason for this？

When I use the ParaView module in trame to implement post-processing visualization, the vtk data for each frame is about 160M. It takes about 20 seconds to refresh a single frame on the page. What could be the reason for this, and what are the possible solutions?

Are you using remote rendering or local rendering? How long does it take in ParaView Qt application?

[camel-lwt]

I have tried both modes, and both are quite laggy. In QT ParaView, each frame takes 0.5 seconds to refresh.

You should get 0.5 seconds in Remote rendering unless you are doing something wrong. But since you did not provide any information, that's all I can say.
