Thanks

Programs and objects stored in port 0 are accessed and executed directly, while objects in ports 1 and 2 require the calculator O/S to perform bank switching (and possibly copying of the objects to temporary memory as well). Generally speaking, this means that executing code from port 0 will perform better than the same code stored in port 1 or 2.

The delay of a single port 1/2 object being accessed is negligible, but if you are executing a program repeatedly, say in a loop, the accumulated effect is noticeable.
