Can you establish how long your simulation takes for two (2) events without trajectories; e.g. without:

/vis/scene/add/trajectories

then with the above but without:

/vis/scene/endOfEventAction accumulate

and finally with:

/vis/scene/endOfEventAction accumulate

I don't understand why the type of drawing trajectories should have any bearing on the length it takes to simulate photon tracks in the event. Sure, with storing and filling large number of trajectories so they can be drawn will slow the simulation somewhat, but not whether the scene is refreshed or not at the end of event....

This sure is strange. I am not an expert with the visualization but even with 'accumulate' the trajectories of one event should be deleted after they have been drawn and before the next event starts. You must be doing something more with the trajectories - perhaps they don't get deleted(?)
