NetworkCollider causing excessive GC / Callbacks

[FirstGearGames]

Reported by @smakis <@!179230126863679488> on Discord.

Constant allocations and callbacks are occurring when a CSP object remains in a NetworkCollider.

Instructions:

• Start Editor1 as server.
• Start Editor2 as client.
• Open TestScene on both editors.
• On Editor2 use keys A/D to roll the player ball into collider object (Boost), Cube in scene; stay in the collider.
• Monitor callbacks and allocations.

Planned investigation shortly after the release of 4.6.9

Just upvoting this. I'm experiencing this behaviour while testing collisions.
@FirstGearGames do you think that using the first collision would be a safe workaround while whe dont have a fix for it?

[FirstGearGames]

The issue appears to be resolved on my test as well using the test project above.

Here's the package with all needed files for 3D and 2D.

Just looking at the fix, NetworkColliderBase does TimeManager.OnPrePhysicsSimulation += TimeManager_OnPostPhysicsSimulation; which may be correct but is confusingly named.

You're right, thanks!
