Below is the SASWORK throughput requirement that you should remember while architecting: Write - 100MB/second for each CPU core Read - 100MB/second for each CPU core This can be calculated using the script attached in this article -> https://support.sas.com/kb/51/660.html Reference -> https://blogs.sas.com/content/sgf/2014/10/08/configuring-sas-what-to-know-before-you-install/ If you are not able to download the script you can copy it from here .

 It is always confusing as in which parameter to use for garbage collection. We can collect garbage collection statistics by using below option: -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps The above option will spit out how often garbage collection occurs and how much time is spent on garbage collection.
