Dear All,

I am looking for tools to measure the rendering performance on client side for VTKWeb. For ParaviewWeb-based client there is a class RemoteRendererStatsTable that collects detailed information on performance process ( roundTrip, workTime, deltaT, RenderCount,StaleRenderCount). I was wondering if there is something similar for VTK.js-based client. As far the only tool I found was vtkFPSMonitor, is it a correct one or there are some other more detailed/specialised tools to use?

Thank you very much in advance,  
Best regards,  
Evgeniya

The `vtkFPSMonitor` is really for the local WebGL rendering not for the remote rendering. But the [ViewStream](https://github1s.com/Kitware/vtk-js/blob/HEAD/Sources/IO/Core/ImageStream/ViewStream.js) does capture some stats… I think we are just missing the display part…

Thank you very much, ViewStream has all info that I need.
