Cycles render [Full GI preset - 128 bounces every channel] 1440x1080
Render farm test (I5-9400f GTX 660Ti 48gb RAM / I7-3770k 16gb RAM / I5-8265u 8gb RAM) 50 frames done in less than 1h (some issues but I'm not sure)
Rigid body is 240 iterations + 32 Iterations solver - pretty stable
Just in case I used Alembic geometry cashe. Marble texture from CC0 Textures https://ambientcg.com/view?id=Tiles074. HDRI from Polyhaven https://polyhaven.com/a/spiaggia_di_mondello.
