The sun goes not through the glas.
Use a HDR-Background and Pathtracing.
The watersurface should also be closed, not only a plane.

A good question, maybe factor 2-3, against from the number of maxdepth...

Maybe you can reduce the maxdepth to 3 or 4...

Ok 2mio polys aren“t a few.
Maybe you can cleanup your scene, that would speedup it too...
