The cost here is $P_R + P_R \cdot P_S$ I/Os, where $P_X$ is the number of pages in the relation $X$.
The cost here is \cost{$P_R + P_R \cdot P_S$ I/Os}, where $P_X$ is the number of pages in the relation $X$.
Furthermore, the DBMS should put the smaller relation on the outer loop to improve performance.
