Multiple cameras on the dashboard makes cpu go crazy, is this a typical homeassistant constraint, or am doing something silly?

HA runs on UTM with 4gig memory.

I just have two TAPO cameras with Generic Camera integration and one RING with ring -MQTT integration.

When I use any of the two in my dashboards, the cpu goes crazy.

I see people complain about this but also see people with 5 camera dashboards.

What am I doing wrong? Thanks!
