I have an issue with what I try to achieve. I want a block to fall down and it's pieces to fall down again and based on the subfracture fracture into smaller pieces. currently I have 2 types of constraints but I could not get the result that I want with just the 2 constraint. I deactivated one of them and am doing the subfracture based on hit attribute which is not very useful because everything fracture at once. please take a look at my file and see if you can help. thanks

سلام خانم خادم امیدوارم حالتون خوب باشه.

Why didn't you use the impulse attribute provided by the glue constraint itself?

I cleaned your dynamic network a bit and set the strength attribute in SOP to -1.
Setting this attribute to -1 in conjunction with using a Primitive Wrangle to look up the break threshold separately will result in faster simulation than a very high strength number since the bullet tries to look up the break threshold on every frame.
I attached the project file and correct it based on the impulse also notice how much it's faster now.

Please keep me posted if you still have trouble.

Hope it helps.
