Ok, I enabled igmpsnooping on the switch (all ports)
set igmpsnooping adminmode enable
set igmpsnooping interfacemode ge.*.*;tg.*.* enable
and additionally the router
ip igmp
interface vlan 123
ip igmp enable
It didn't help much really....

In fact all our G3's are at 20%-30% CPU even if nothing or not much is happening
on them. Wondering if that's normal.
