 s3-benchmark is a program for performing S3 operations PUT, GET, and DELETE for objects.  Besides the 
 bucket configuration, the object size and number of threads can be given for different tests.

+#Note
+Your benchmark results may vary most often because of limitations of your network connection to the cloud storage
+provider.  Wasabi performance claims are tested under conditions that remove any latency (which can be shown using 
+the ping command) and bandwidth bottlenecks that restrict how fast data can be moved.  For more information,
