Particle system hitches entire game thread

hello

I’d like to know how can I tackle this issue. When I execute the activate node on the particle system for the first time, the whole game stutters for a split second.

After that initial game hitch, no matter how many times I activate the particle system again, there is no more stutter. I’ve tried using the warm-up property in the particle system, but it doesn’t solve this problem.

Note: This only happens on android and iOS
