Primitive Function Performance of APL2

This document reports the results of timings of the Vector Facility (VF) support available on an IBM 3090/S processor using APL2 Version I Release 3 (with SPE PL34409). Included are execution times for selected primitive functions and expressions. The measurements were first taken with the VF utilization turned off and then again with the VF utilization turned on. The ratios scaIar+vector are also reported.
