you can easly use libs like blocks and see how its done there
every Geom = drawcall, so you should have not much Geoms, tho 200 geoms should not be too much anyway. The thing is on screenshot i see 7000+ objects since you probably use shadows/filters that multiple it very much. Or you just have too many Geoms, idk.
In fact with 200 Quads shhould be as 1 Geom rly.
Like suggested you can also see with profiler state to see and solve problem you got.
