I tried something more simple
With two kids
acl users src 10.0.0.0/8
delay_pools 1
delay_class 1 2
delay_parameters 1 1625000/1625000 64000/64000 // 13 Mbits/by workers and 512kbits/user
delay_access 1 allow users
delay_access 1 deny all
My physical bandwidth max is 50 Mbits
After five/ten minutes, squid seems inusable - very very slow - But I saw nothing special with squidclient
