Using Benchmarks to Compare Techniques
To decide which SAS programming technique is most
efficient for a particular task, you can benchmark (measure and compare)
the resource usage for each technique that you are comparing. You
should benchmark with the actual data to determine the most efficient
Guidelines for Benchmarking
Your benchmarking is most likely to yield useful results
if you follow these guidelines:
Before you test the programming
techniques, turn on the SAS system options that report resource usage.
As explained earlier, to track and report on resource usage, you can use some or all of the system options STIMER, MEMRPT, FULLSTIMER, and STATS. The availability, usage, and functionality of these options vary by operating ...
