object cleanup when not relevant

hello guys!

I have a question regarding cleaning objects:

I'm working on a networked game where the server send each client states of objects that are nearby that player on each tick, w$$anonymous$$ch the client interpolates and visualizes said objects. I want to clean ($$anonymous$$de or dispose) objects that are not updated for X time.

I came up with t$$anonymous$$s solution: Create a "cleaning" w$$anonymous$$ch receives a CancelationTokenSource and will wait for a timeout and then call the cleaning action. if canceled (meaning an update for that object had arrived) then I'll recreate that task. Will performance be an issue for such a mechanism where I might end up with dozens or hundreds of tasks running at the same time? would it be better to simply check on every tick of all the synced objects, w$$anonymous$$ch is no longer updated (for more than a few ticks)?

If you could suggest a better approach for t$$anonymous$$s problem it would be very helpful!
